首先简单的介绍下fragment,fragment是android3.0新增的概念,其中文意思是碎片,它与activity非常相似,用来在一个activity中描述一些行为或一部分用户界面。使用锁个fragment可以再一个单独的activity中建立多个UI面板,也可以在多个activity中重用fragment,一个fragment必须被嵌入到一个activity中,它的生命周期直接受其所宿主的activity的生命周期的影响。
首先创建一个fragment,要创建一个fragment,必须创建一个fragment的子类,或者继承自另外一个已经存在的Fragment的子类,并重写相应的方法。
编写Fragment的xml文件和类文件,这里我写了四个,贴出来其中两个代码,其他的copy就行。
fragment_main.xml
MainFragment.java
fragment_grxx.xml
GrxxFragment.java
自定义底部工具栏
FragmentIndicator.java
自定义顶部工具栏
title_view.xml
TitleView.java
在main.xml里面添加相关fragment和自定义底部工具栏,注意name属性
在主线程中对fragment做相关操作
运行相关效果图

fragment_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity" > <TextView android:layout_height="wrap_content" android:layout_width="wrap_content" android:gravity="center" android:text="主页面" /> </RelativeLayout>
MainFragment.java
public class MainFragment extends Fragment{ @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.fragment_main, container,false); return view; } @Override public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); } }
fragment_grxx.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity" > <com.qyh.view.TitleView android:id="@+id/title" android:layout_width="match_parent" android:layout_height="wrap_content" /> <TextView android:layout_height="wrap_content" android:layout_width="wrap_content" android:gravity="center" android:text="个人信息" /> </RelativeLayout>
GrxxFragment.java
public class GrxxFragment extends Fragment{ private TitleView titleView; private FragmentActivity mActivity; private View mParent; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.fragment_grxx, container,false); return view; } @Override public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); mActivity = getActivity(); mParent = getView(); titleView = (TitleView) mActivity.findViewById(R.id.title); titleView.setTitle("个人信息"); titleView.setBackButton(new TitleView.OnBackButtonClickListener() { @Override public void onClick(View button) { getFragmentManager().beginTransaction() .hide(com.qyh.main.MainActivity.mFragments[1]) .show(com.qyh.main.MainActivity.mFragments[0]).commit(); FragmentIndicator.setIndicator(0); } }); } }
自定义底部工具栏
FragmentIndicator.java
public class FragmentIndicator extends LinearLayout implements OnClickListener { private static String TAG = "FragmentIndicator"; private int mDefaultIndicator = 0;// 默认位置 private static int mCurIndicator;// 当前位置 private static View[] mIndicators; private OnIndicateListener mOnIndicateListener; private static final String TAG_ICON_0 = "icon_tag_0"; private static final String TAG_ICON_1 = "icon_tag_1"; private static final String TAG_ICON_2 = "icon_tag_2"; private static final String TAG_ICON_3 = "icon_tag_3"; private FragmentIndicator(Context context) { super(context); } public FragmentIndicator(Context context, AttributeSet attrs) { super(context, attrs); mCurIndicator = mDefaultIndicator; setOrientation(LinearLayout.HORIZONTAL); initView(); } private View createIndicator(int iconResID, int stringResID, int stringColor, String iconTag, String textTag) { LinearLayout view = new LinearLayout(getContext()); view.setOrientation(LinearLayout.HORIZONTAL); view.setLayoutParams(new LinearLayout.LayoutParams( LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT,1)); view.setGravity(Gravity.CENTER); ImageView iconView = new ImageView(getContext()); iconView.setTag(iconTag); iconView.setLayoutParams(new LinearLayout.LayoutParams( LayoutParams.WRAP_CONTENT, LayoutParams.MATCH_PARENT, 1)); iconView.setImageResource(iconResID); view.addView(iconView); return view; } private void initView() { mIndicators = new View[4]; mIndicators[0] = createIndicator(R.drawable.main_home, 0, 0, TAG_ICON_0, null); mIndicators[0].setBackgroundResource(R.drawable.indic_select); mIndicators[0].setTag(Integer.valueOf(0)); mIndicators[0].setOnClickListener(this); addView(mIndicators[0]); mIndicators[1] = createIndicator(R.drawable.main_user, 0, 0, TAG_ICON_1, null); mIndicators[1].setBackgroundResource(Color.alpha(0)); mIndicators[1].setTag(Integer.valueOf(1)); mIndicators[1].setOnClickListener(this); addView(mIndicators[1]); mIndicators[2] = createIndicator(R.drawable.main_set, 0, 0, TAG_ICON_2, null); mIndicators[2].setBackgroundResource(Color.alpha(0)); mIndicators[2].setTag(Integer.valueOf(2)); mIndicators[2].setOnClickListener(this); addView(mIndicators[2]); mIndicators[3] = createIndicator(R.drawable.main_more, 0, 0, TAG_ICON_3, null); mIndicators[3].setBackgroundResource(Color.alpha(0)); mIndicators[3].setTag(Integer.valueOf(3)); mIndicators[3].setOnClickListener(this); addView(mIndicators[3]); } public static void setIndicator(int which) { // 以前状态 mIndicators[mCurIndicator].setBackgroundColor(Color.alpha(0)); ImageView prevIcon; switch (mCurIndicator) { case 0: prevIcon = (ImageView) mIndicators[mCurIndicator] .findViewWithTag(TAG_ICON_0); prevIcon.setImageResource(R.drawable.main_home); break; case 1: prevIcon = (ImageView) mIndicators[mCurIndicator] .findViewWithTag(TAG_ICON_1); prevIcon.setImageResource(R.drawable.main_user); break; case 2: prevIcon = (ImageView) mIndicators[mCurIndicator] .findViewWithTag(TAG_ICON_2); prevIcon.setImageResource(R.drawable.main_set); break; case 3: prevIcon = (ImageView) mIndicators[mCurIndicator] .findViewWithTag(TAG_ICON_3); prevIcon.setImageResource(R.drawable.main_more); break; default: break; } Log.i(TAG, "setIndicator:mCurIndicator=" + mCurIndicator); // 更新当前状态 mIndicators[which].setBackgroundResource(R.drawable.indic_select); ImageView currIcon; switch (which) { case 0: currIcon = (ImageView) mIndicators[which] .findViewWithTag(TAG_ICON_0); currIcon.setImageResource(R.drawable.main_home_hover);// 选中后的图片 break; case 1: currIcon = (ImageView) mIndicators[which] .findViewWithTag(TAG_ICON_1); currIcon.setImageResource(R.drawable.main_user_hover); break; case 2: currIcon = (ImageView) mIndicators[which] .findViewWithTag(TAG_ICON_2); currIcon.setImageResource(R.drawable.main_set_hover); break; case 3: currIcon = (ImageView) mIndicators[which] .findViewWithTag(TAG_ICON_3); currIcon.setImageResource(R.drawable.main_more_hover); break; default: break; } mCurIndicator = which; } public interface OnIndicateListener { public void onIndicate(View v, int which); } public void setOnIndicateListener(OnIndicateListener listener) { mOnIndicateListener = listener; } @Override public void onClick(View v) { if (mOnIndicateListener != null) { int tag = (Integer) v.getTag(); switch (tag) { case 0: if (mCurIndicator != 0) { mOnIndicateListener.onIndicate(v, 0); setIndicator(0); } break; case 1: if (mCurIndicator != 1) { mOnIndicateListener.onIndicate(v, 1); setIndicator(1); } break; case 2: if (mCurIndicator != 2) { mOnIndicateListener.onIndicate(v, 2); setIndicator(2); } break; case 3: if (mCurIndicator != 3) { mOnIndicateListener.onIndicate(v, 3); setIndicator(3); } break; default: break; } } } }
自定义顶部工具栏
title_view.xml
<?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="48dip" android:background="#18222E" > <ImageButton android:id="@+id/ib_back" android:layout_width="48dp" android:layout_height="match_parent" android:src="@drawable/ic_titleback" /> <TextView android:id="@+id/tv_title" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_gravity="center" android:text="个人信息"/> <ImageButton android:id="@+id/ib_handle" android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_gravity="right" android:layout_marginRight="12dp" android:visibility="gone"/> </FrameLayout>
TitleView.java
/** * 功能描述:自定义顶部工具栏 */ public class TitleView extends FrameLayout implements View.OnClickListener { public OnBackButtonClickListener mOnBackButtonClickListener; public OnHandleButtonClickListener mHandleButtonClickListener; private TextView mTitle; private ImageButton mBackButton; private ImageButton ib_handle; public TitleView(Context context) { this(context, null); } public TitleView(Context context, AttributeSet attrs) { this(context, attrs, 0); } public TitleView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); LayoutInflater inflater = (LayoutInflater) context .getSystemService(Context.LAYOUT_INFLATER_SERVICE); inflater.inflate(R.layout.title_view, this, true); mBackButton = (ImageButton) findViewById(R.id.ib_back); mBackButton.setOnClickListener(this); mTitle = (TextView) findViewById(R.id.tv_title); mTitle.setVisibility(View.INVISIBLE); ib_handle = (ImageButton) findViewById(R.id.ib_handle); ib_handle.setOnClickListener(this); } public interface OnBackButtonClickListener { public void onClick(View button); } public interface OnHandleButtonClickListener { public void onClick(View button); } /** * 标题返回按钮 * * @param listener */ public void setBackButton(OnBackButtonClickListener listener) { mOnBackButtonClickListener = listener; } public void showBackBtn(){ mBackButton.setVisibility(View.VISIBLE); } public void hiddenBackBtn(){ mBackButton.setVisibility(View.GONE); } /** * 标题操作按钮 * * @param listener */ public void setHandleButton(OnHandleButtonClickListener listener) { mHandleButtonClickListener = listener; } public void hiddenHandleBtn(){ ib_handle.setVisibility(View.GONE); } public void showHandleBtn(int iamgeBtnID){ ib_handle.setImageResource(iamgeBtnID); ib_handle.setVisibility(View.VISIBLE); } //设置标题 public void setTitle(String text) { mTitle.setVisibility(View.VISIBLE); mTitle.setText(text); } public void setTitle(int stringID) { mTitle.setVisibility(View.VISIBLE); mTitle.setText(stringID); } @Override public void onClick(View v) { switch (v.getId()) { case R.id.ib_back: if (mOnBackButtonClickListener != null) { mOnBackButtonClickListener.onClick(v); } break; case R.id.ib_handle: if (mHandleButtonClickListener != null) { mHandleButtonClickListener.onClick(v); } break; default: break; } } }

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <fragment android:id="@+id/fragment_main" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1" android:name="com.qyh.fragment.MainFragment" /> <fragment android:id="@+id/fragment_grxx" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1" android:name="com.qyh.fragment.GrxxFragment" /> <fragment android:id="@+id/fragment_sz" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1" android:name="com.qyh.fragment.SzFragment" /> <fragment android:id="@+id/fragment_others" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1" android:name="com.qyh.fragment.OthersFragment" /> <!--此处为自定义底部菜单栏 --> <com.qyh.fragment.FragmentIndicator android:id="@+id/indicator" android:layout_width="fill_parent" android:layout_height="48dp" /> </LinearLayout>
在主线程中对fragment做相关操作
public class MainActivity extends FragmentActivity { public static Fragment[] mFragments; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.activity_main); setFragmentIndicator(0); } private void setFragmentIndicator(int whichIsDefault) { mFragments = new Fragment[4]; mFragments[0] = getSupportFragmentManager().findFragmentById( R.id.fragment_main); mFragments[1] = getSupportFragmentManager().findFragmentById( R.id.fragment_grxx); mFragments[2] = getSupportFragmentManager().findFragmentById( R.id.fragment_sz); mFragments[3] = getSupportFragmentManager().findFragmentById( R.id.fragment_others); getSupportFragmentManager().beginTransaction().hide(mFragments[0]) .hide(mFragments[1]).hide(mFragments[2]).hide(mFragments[3]) .show(mFragments[whichIsDefault]).commit(); FragmentIndicator mIndicator = (FragmentIndicator) findViewById(R.id.indicator); FragmentIndicator.setIndicator(whichIsDefault); mIndicator.setOnIndicateListener(new OnIndicateListener() { @Override public void onIndicate(View v, int which) { getSupportFragmentManager().beginTransaction() .hide(mFragments[0]).hide(mFragments[1]) .hide(mFragments[2]).hide(mFragments[3]) .show(mFragments[which]).commit(); } }); } }
