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。

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 this.setWidth(LayoutParams.FILL_PARENT); // 设置SelectPicPopupWindow弹出窗体的高 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() { * * 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" 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 { 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 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。
