最简单的实现方式:布局xml
最简单的实现方式:
布局xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:onClick="bt_qiehuan"
android:layout_width="350dp"
android:layout_height="150dp"
android:orientation="vertical"
tools:context=".make_layout.ViewLayoutActivity">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginRight="10dp"
android:layout_weight="1"
android:background="#455D9D"
android:orientation="horizontal">
<!--开设置-->
<LinearLayout
android:id="@+id/ll_morentype1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="visible">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center"
android:text="开"
android:textColor="@color/white"
android:textSize="30sp" />
<ImageButton
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1" />
</LinearLayout>
<!--关设置-->
<LinearLayout
android:id="@+id/ll_morentype2"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="gone">
<ImageButton
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1" />
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center"
android:text="关"
android:textColor="@color/white"
android:textSize="30sp"
/>
</LinearLayout>
</LinearLayout>
</LinearLayout>
代码:
public class ViewLayoutActivity extends AppCompatActivity {
private boolean qiehuan_boolean = false; //默认 true:开 false:关
LinearLayout ll_morentype1,ll_morentype2;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_view_layout);
ll_morentype1=findViewById(R.id.ll_morentype1);
ll_morentype2=findViewById(R.id.ll_morentype2);
}
public void bt_qiehuan(View view) {
if (qiehuan_boolean == true) {
ll_morentype1.setVisibility(View.VISIBLE);
ll_morentype2.setVisibility(View.GONE);
qiehuan_boolean = false;
} else {
ll_morentype1.setVisibility(View.GONE);
ll_morentype2.setVisibility(View.VISIBLE);
qiehuan_boolean = true;
}
}
}
这样就可以简单的实现开关的效果了
当然,能封装一下就好了:
1.将上面的逻辑和布局复制一份:新建一个类TitleLinearLayout
public class TitleLinearLayout extends LinearLayout {
private boolean qiehuan_boolean = false; //默认 true:开 false:关
LinearLayout ll_morentype1,ll_morentype2,ll_qiehuan;
Tabstutas tabstutas;
public TitleLinearLayout(Context context) {
super(context);
}
public TitleLinearLayout(Context context, @Nullable AttributeSet attrs) {
super(context, attrs);
View.inflate(context, R.layout.activity_view_layout,this);
ll_morentype1=findViewById(R.id.ll_morentype1);
ll_morentype2=findViewById(R.id.ll_morentype2);
ll_qiehuan=findViewById(R.id.ll_qiehuan);
ll_qiehuan.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if(tabstutas!=null){
if (qiehuan_boolean == true) {
ll_morentype1.setVisibility(View.VISIBLE);
ll_morentype2.setVisibility(View.GONE);
qiehuan_boolean = false;
tabstutas.cheak(true);
} else {
ll_morentype1.setVisibility(View.GONE);
ll_morentype2.setVisibility(View.VISIBLE);
qiehuan_boolean = true;
tabstutas.cheak(false);
}
}
}
});
}
public void setlistnear(Tabstutas tabstutas){
this.tabstutas=tabstutas;
}
interface Tabstutas{
void cheak(boolean stutas);
}
}
2.新建一个布局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/ll_qiehuan"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
tools:context=".make_layout.ViewLayoutActivity">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginRight="10dp"
android:layout_weight="1"
android:background="#455D9D"
android:orientation="horizontal">
<!--开设置-->
<LinearLayout
android:id="@+id/ll_morentype1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="visible">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center"
android:text="开"
android:textColor="@color/white"
android:textSize="30sp" />
<ImageButton
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1" />
</LinearLayout>
<!--关设置-->
<LinearLayout
android:id="@+id/ll_morentype2"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="gone">
<ImageButton
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1" />
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center"
android:text="关"
android:textColor="@color/white"
android:textSize="30sp"
/>
</LinearLayout>
</LinearLayout>
</LinearLayout>
2.测试页面使用
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="350dp"
android:layout_height="150dp"
android:orientation="vertical"
tools:context=".make_layout.ViewLayoutActivity">
<com.example.test_01.make_layout.TitleLinearLayout
android:id="@+id/ll_stutas"
android:layout_width="200dp"
android:layout_height="100dp"/>
</LinearLayout>
public class ViewLayoutActivity extends AppCompatActivity {
TitleLinearLayout ll_stutas;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_viewlayout);
ll_stutas=findViewById(R.id.ll_stutas);
ll_stutas.setlistnear(new TitleLinearLayout.Tabstutas() {
@Override
public void cheak(boolean stutas) {
Log.i("点击的状态", "cheak: "+stutas);
}
});
}
}
简单封装了实现开关按钮的效果和状态输出,当然这样这是很简陋的,如果你有更好的改良方式都可以在自定义类TitleLinearLayout里面增加其他方法 。
