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;

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 this.setWidth(LayoutParams.FILL_PARENT);
// 设置SelectPicPopupWindow弹出窗体的高 WindowManager wm = (WindowManager) context .getSystemService(Context.WINDOW_SERVICE);

// 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.setOnTouchListener(new OnTouchListener() {

}
}
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();
}

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 {
/** * 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, 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);
}
/** * 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 {

}
}

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 start, int count, int after) {
setClearIconVisible(s.length() > 0);
}
@Override public void beforeTextChanged(CharSequence s, int start, int count, 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, 0);
translateAnimation.setInterpolator(new CycleInterpolator(counts));
translateAnimation.setDuration(1000);
return translateAnimation;
}
}
一些icon 及圆角背景就不展示了。
