Android View 完美实现EditText 在软键盘上边的示例

概述此方法基于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。

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SelectPicPopupWindowd出窗体的宽  this.setWIDth(LayoutParams.FILL_PARENT);  // 设置SelectPicPopupWindowd出窗体的高  WindowManager wm = (WindowManager) context      .getSystemService(Context.WINDOW_SERVICE);//  this.setHeight(wm.getDefaultdisplay().getHeight() / 2);  this.setHeight(LayoutParams.WRAP_CONTENT);  // 设置SelectPicPopupWindowd出窗体可点击  this.setFocusable(true);  // 设置SelectPicPopupWindowd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SelectPicPopupWindowd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d出框  /*   * popVIEw.setontouchListener(new OntouchListener() {   *    * public boolean ontouch(VIEw v,MotionEvent event) {   *    * int height = popVIEw.findVIEwByID(R.ID.pop_layout).gettop(); int   * y=(int) event.getY(); if(event.getAction()==MotionEvent.ACTION_UP){   * if(y<height){ dismiss(); } } return true; } });   */  (popVIEw.findVIEwByID(R.ID.btn_back)).setonClickListener(new OnClickListener() {    @OverrIDe    public voID onClick(VIEw v) {       dismiss();    }  });  (popVIEw.findVIEwByID(R.ID.btn_right)).setonClickListener(new OnClickListener() {    @OverrIDe    public voID onClick(VIEw v) {      if(onheadClickListener!=null){        onheadClickListener.okListener();      }      if(isOkClose){        dismiss();      }    }  });  if(isOpenKeyboard){    openKeyboard();  }}public boolean isShowTitle() {  return isShowTitle;}public voID setShowTitle(boolean 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){  if(tv_head!=null){    tv_head.setText(value);  }}public boolean isOkClose() {  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"        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"        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"        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 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);}

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 { /** * 删除按钮的引用 */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,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,mClearDrawable.getIntrinsicWIDth(),mClearDrawable.getIntrinsicHeight());   setClearIconVisible(false);   setonFocuschangelistener(this);   addTextChangedListener(this); } /** * 因为我们不能直接给EditText设置点击事件，所以我们用记住我们按下的位置来模拟点击事件 * 当我们按下的位置 在 EditText的宽度 - 图标到控件右边的间距 - 图标的宽度 和 * EditText的宽度 - 图标到控件右边的间距之间我们就算点击了图标，竖直方向没有考虑 */@OverrIDe public boolean ontouchEvent(MotionEvent event) {   if (getCompoundDrawables()[2] != null) {     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); } /** * 当ClearEditText焦点发生变化的时候，判断里面字符串长度设置清除图标的显示与隐藏 */@OverrIDe public voID onFocusChange(VIEw v,boolean hasFocus) {   if (hasFocus) {     setClearIconVisible(getText().length() > 0);   } else {     setClearIconVisible(false);   } } /** * 设置清除图标的显示与隐藏，调用setCompoundDrawables为EditText绘制上去 * @param visible */protected voID setClearIconVisible(boolean visible) {   Drawable right = visible ? mClearDrawable : null;   setCompoundDrawables(getCompoundDrawables()[0],getCompoundDrawables()[1],right,getCompoundDrawables()[3]); } /** * 当输入框里面内容发生变化的时候回调的方法 */@OverrIDe public voID onTextChanged(CharSequence s,int after) {   setClearIconVisible(s.length() > 0); } @OverrIDe public voID beforeTextChanged(CharSequence s,int after) { } @OverrIDe public voID afterTextChanged(Editable s) { } /** * 设置晃动动画 */public voID setShakeAnimation(){  this.setAnimation(shakeAnimation(5));}/** * 晃动动画 * @param counts 1秒钟晃动多少下 * @return */public static Animation shakeAnimation(int counts){  Animation translateAnimation = new TranslateAnimation(0,10,0);  translateAnimation.setInterpolator(new CycleInterpolator(counts));  translateAnimation.setDuration(1000);  return translateAnimation;}}

一些icon 及圆角背景就不展示了。
