Android View 完美实现EditText 在软键盘上边的示例

此方法基于popupwindow,适合需要回复内容时响应点击事件，打开软键盘，编辑框在软键盘上部。
优点，编辑框使用cleanedittext,监听输入状态来更改回复按钮颜色，添加title等。

先展示效果

点击评论打开软键盘，编辑框在软键盘上部，点击其他区域消失收起软键盘：

1.baseselectpopupwindow 的代码。

public class baseselectpopupwindow extends popupwindow {

private view popview;

private view view;


private onheadclicklistener onheadclicklistener;


private textview tv_head;


protected context context;


private boolean isopenkeyboard=false;;


private boolean isshowtitle=true;

private boolean isokclose=true;


protected int maxtextsize = 24;
protected int mintextsize = 14;
public baseselectpopupwindow(context context, int layoutid ) {

  this.context=context;
  layoutinflater inflater = (layoutinflater) context
      .getsystemservice(context.layout_inflater_service);
  popview = inflater.inflate(r.layout.pop_view, null);
  tv_head=(textview) popview.findviewbyid(r.id.tv_head);

  linearlayout contentview = (linearlayout) popview
      .findviewbyid(r.id.content);
  view=inflater.inflate(layoutid, null);
  contentview.addview(view,contentview.getlayoutparams());
  // btn_take_photo.setonclicklistener(itemsonclick);
  // 设置selectpicpopupwindow的view
  this.setcontentview(popview);
  // 设置selectpicpopupwindow弹出窗体的宽

  windowmanager wm = (windowmanager) context
      .getsystemservice(context.window_service);
//  this.setheight(wm.getdefaultdisplay().getheight() / 2);
  this.setheight(layoutparams.wrap_content);
  // 设置selectpicpopupwindow弹出窗体可点击
  this.setfocusable(true);
  // 设置selectpicpopupwindow弹出窗体动画效果
  this.setanimationstyle(r.style.animbottom);
  // 实例化一个colordrawable颜色为半透明
  colordrawable dw = new colordrawable(0xb0000000);
  // 设置selectpicpopupwindow弹出窗体的背景
  this.setbackgrounddrawable(dw);
  // mmenuview添加ontouchlistener监听判断获取触屏位置如果在选择框外面则销毁弹出框

  /*

   */

  (popview.findviewbyid(r.id.btn_back)).setonclicklistener(new onclicklistener() {

    @override
    public void onclick(view v) {
       dismiss();
    }
  });

      if(onheadclicklistener!=null){
        onheadclicklistener.oklistener();
      }
      if(isokclose){

      }

    }
  });

  if(isopenkeyboard){
    openkeyboard();
  }



}
public boolean isshowtitle() {
  return isshowtitle;
}

  this.isshowtitle = isshowtitle;
  if(!isshowtitle){
    ((relativelayout)tv_head.getparent()).setvisibility(view.gone);
  }
}
/**
 * 打开软键盘
 */
private void openkeyboard() {

    timer timer = new timer();
    timer.schedule(new timertask() {
        @override
        public void run() {
            inputmethodmanager imm = (inputmethodmanager) context.getsystemservice(context.input_method_service);
            imm.togglesoftinput(0, inputmethodmanager.hide_not_always);

        }
    }, 1000);
}
public boolean isopenkeyboard() {
  return isopenkeyboard;
}
public void setopenkeyboard(boolean isopenkeyboard) {
  this.isopenkeyboard = isopenkeyboard;
}

public onheadclicklistener getonheadclicklistener() {
  return onheadclicklistener;
}

public void setonheadclicklistener(onheadclicklistener onheadclicklistener) {
  this.onheadclicklistener = onheadclicklistener;
}

public interface onheadclicklistener{
  public void oklistener();
}



public void settitle(string value){

  return isokclose;
}
public void setokclose(boolean isokclose) {
  this.isokclose = isokclose;
}
public context getcontext() {
  return context;
}

对应的xml 布局：

<?xml version="1.0" encoding="utf-8"?>
<relativelayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/white_gray"
android:gravity="center_vertical" >

<relativelayout
  android:id="@+id/head"
  android:layout_width="match_parent"
  android:layout_height="44dp"
  android:layout_alignparenttop="true"
  android:background="@color/head_yellow" >

  <textview
    android:id="@+id/btn_back"
    style="@style/nav_side_title_text"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignparentleft="true"
    android:layout_centervertical="true"
    android:layout_marginleft="15dp"
    android:text="@string/cancel"
    android:textcolor="@color/black_light_color"
    android:textsize="@dimen/titletextsize" />

  <textview
    android:id="@+id/tv_head"
    style="@style/nav_head_title_text"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:ellipsize="end"
    android:gravity="center"
    android:visibility="gone" />

  <textview
    android:id="@+id/btn_right"
    style="@style/nav_side_title_text"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignparentright="true"
    android:layout_centervertical="true"
    android:layout_marginright="15dp"
    android:text="@string/sure"
    android:textcolor="@color/black"
    android:textsize="@dimen/titletextsize" />
</relativelayout>

<linearlayout
  android:id="@+id/content"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:layout_below="@id/head"
  android:gravity="center"
  android:orientation="vertical" >
 </linearlayout>

</relativelayout>

其中style:nav_side_title_text是定义文字大小的。

2.需要使用的时候

private baseselectpopupwindow popwiw;// 回复的 编辑框

声明之后使用的时候初始化并调用：

 private void popwiw( ) {

  popwiw = new baseselectpopupwindow(context, r.layout.edit_data);
  // popwiw.setopenkeyboard(true);
  popwiw.setinputmethodmode(popupwindow.input_method_needed);
  popwiw.setfocusable(true);
  popwiw.setsoftinputmode(windowmanager.layoutparams.soft_input_adjust_resize);
  popwiw.setshowtitle(false);
  inputmethodmanager im = (inputmethodmanager) context
      .getsystemservice(context.input_method_service);
  im.togglesoftinput(0, inputmethodmanager.hide_not_always);

  final button send = (button) popwiw.getcontentview().findviewbyid(
      r.id.btn_send);
  final edittext edt = (edittext) popwiw.getcontentview().findviewbyid(
      r.id.edt_content);

  edt.setinputtype(editorinfo.type_class_text);
  edt.setimeoptions(editorinfo.ime_action_send);
  edt.addtextchangedlistener(new textwatcher() {

    @override
    public void ontextchanged(charsequence s, int start, int before,
                 int count) {
      if (textutils.isempty(edt.gettext())) {
        send.setenabled(false);
      } else {
        send.setenabled(true);
      }
    }

    @override
    public void beforetextchanged(charsequence s, int start, int count,
                   int after) {

    }

    @override
    public void aftertextchanged(editable s) {
      // todo auto-generated method stub

    }
  });
  edt.setoneditoractionlistener(new textview.oneditoractionlistener() {

    @override
    public boolean oneditoraction(textview v, int actionid,
                   keyevent event) {
      if (actionid == editorinfo.ime_action_send
          || (event != null && event.getkeycode() == keyevent.keycode_enter)) {

        if (!textutils.isempty(edt.gettext().tostring().trim())) {
      string content = edt.gettext().tostring().trim();
          // /提交内容  sumbit(content)
          popwiw.dismiss();
        }
        return true;
      }
      return false;
    }
  });
  send.setonclicklistener(new view.onclicklistener() {

    @override
    public void onclick(view v) {
      if (!textutils.isempty(edt.gettext().tostring().trim())) {

        // /提交内容
        string content = edt.gettext().tostring().trim();

        popwiw.dismiss();
      }
    }
  });

  popwiw.settitle("回复" + nickname);
  popwiw.showatlocation(refreshlayout, gravity.bottom
      | gravity.center_horizontal, 0, 0);
}

对应的edit_data xml布局

<?xml version="1.0" encoding="utf-8"?>
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="55dp" >

<relativelayout
  android:layout_width="match_parent"
  android:layout_height="44dp"
  android:background="@drawable/bg_search"
  android:gravity="clip_vertical"
  android:orientation="vertical"
  android:paddingleft="12dp"
  android:paddingright="12dp" >

  <com.myapp.view.clearedittext
    android:id="@+id/edt_content"
    android:layout_width="match_parent"
    android:layout_height="55dp"
    android:layout_alignparentleft="true"
    android:layout_centervertical="true"
    android:layout_marginbottom="5dp"
    android:layout_marginright="65dp"
    android:layout_margintop="5dp"
    android:background="@drawable/edittext_back"
    android:focusable="true"
    android:hint="说点什么..."
    android:paddingleft="10dp"
    android:imeoptions="actionsend"
    android:paddingright="10dp"
    android:textcolor="@color/top_bg_shadow"
    android:textsize="@dimen/normaltextsize" >
  </com.myapp.view.clearedittext>

  <button
    android:id="@+id/btn_send"
    android:layout_width="60dp"
    android:layout_height="34dp"
    android:layout_alignparentright="true"
    android:layout_centervertical="true"
    android:background="@drawable/btn_send_rounded"
    android:enabled="false"
    android:paddingleft="12dp"
    android:paddingright="12dp"
    android:text="@string/send"
    android:textcolor="@color/white"
    android:textsize="@dimen/normaltextsize" />
</relativelayout>

</linearlayout>

对于clearedittext，应该都不陌生，

public class clearedittext extends edittext implements 
  onfocuschangelistener, textwatcher { 
/**

private drawable mcleardrawable; 

public clearedittext(context context) { 
  this(context, null);

public clearedittext(context context, attributeset attrs) { 
  //这里构造方法也很重要，不加这个很多属性不能再xml里面定义
  this(context, attrs, android.r.attr.edittextstyle); 
} 

public clearedittext(context context, attributeset attrs, int defstyle) {
  super(context, attrs, defstyle);
  init();
}


private void init() { 
  //获取edittext的drawableright,假如没有设置我们就使用默认的图片
  mcleardrawable = getcompounddrawables()[2]; 
  if (mcleardrawable == null) { 
    mcleardrawable = getresources() 
        .getdrawable(r.drawable.icon_edit_del); 
  } 
  mcleardrawable.setbounds(0, 0, mcleardrawable.getintrinsicwidth(), mcleardrawable.getintrinsicheight()); 
  setcleariconvisible(false); 
  setonfocuschangelistener(this); 
  addtextchangedlistener(this); 
} 

/**

 */
@override

    if (event.getaction() == motionevent.action_up) { 
      boolean touchable = event.getx() > (getwidth() 
          - getpaddingright() - mcleardrawable.getintrinsicwidth()) 
          && (event.getx() < ((getwidth() - getpaddingright())));
      if (touchable) { 
        this.settext(""); 
      } 
    } 
  } 

  return super.ontouchevent(event); 
} 

/**

}
}

一些icon 及圆角背景就不展示了。
