废话不多说,先看效果图:
这是主Activity代码:
- public class RollActivity extends Activity {
- private View view;
- private Button btn;
- private PopupWindow mPopupWindow;
- private View[] btns;
- /** Called when the activity is first created. */
- @Override
- public void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- setContentView(R.layout.main);
- // LinearLayout layout=(LinearLayout) view.findViewById(R.id.layout_main);
- // //设置背景图片旋转180
- // Bitmap mBitmap=setRotate(R.drawable.bg_kuang);
- // BitmapDrawable drawable=new BitmapDrawable(mBitmap);
- // layout.setBackgroundDrawable(drawable);
- btn=(Button) this.findViewById(R.id.btn);
- btn.setOnClickListener(new OnClickListener(){
- @Override
- public void onClick(View v) {
- // TODO Auto-generated method stub
- showPopupWindow(btn);
- }
- });
- initPopupWindow(R.layout.popwindow);
- }
- private void initPopupWindow(int resId){
- LayoutInflater mLayoutInflater = (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);
- view = mLayoutInflater.inflate(resId, null);
- mPopupWindow = new PopupWindow(view, 400,LayoutParams.WRAP_CONTENT);
- // mPopupWindow.setBackgroundDrawable(new BitmapDrawable());//必须设置background才能消失
- mPopupWindow.setBackgroundDrawable(getResources().getDrawable(R.drawable.bg_frame));
- mPopupWindow.setOutsideTouchable(true);
- //自定义动画
- // mPopupWindow.setAnimationStyle(R.style.PopupAnimation);
- //使用系统动画
- mPopupWindow.setAnimationStyle(android.R.style.Animation_Dialog);
- mPopupWindow.update();
- mPopupWindow.setTouchable(true);
- mPopupWindow.setFocusable(true);
- btns=new View[3];
- btns[0]=view.findViewById(R.id.btn_0);
- btns[1]=view.findViewById(R.id.btn_1);
- btns[2]=view.findViewById(R.id.btn_2);
- btns[0].setOnClickListener(new OnClickListener() {
- @Override
- public void onClick(View v) {
- // TODO Auto-generated method stub
- //doSomething
- }
- });
- btns[1].setOnClickListener(new OnClickListener() {
- @Override
- public void onClick(View v) {
- // TODO Auto-generated method stub
- //doSomething
- }
- });
- btns[2].setOnClickListener(new OnClickListener() {
- @Override
- public void onClick(View v) {
- // TODO Auto-generated method stub
- //doSomething
- }
- });
- }
- private void showPopupWindow(View view) {
- if(!mPopupWindow.isShowing()){
- // mPopupWindow.showAsDropDown(view,0,0);
- mPopupWindow.showAtLocation(view, Gravity.CENTER, 0, 0);
- }
- }
- public Bitmap setRotate(int resId) {
- Matrix mFgMatrix = new Matrix();
- Bitmap mFgBitmap = BitmapFactory.decodeResource(getResources(), resId);
- mFgMatrix.setRotate(180f);
- return mFgBitmap=Bitmap.createBitmap(mFgBitmap, 0, 0,
- mFgBitmap.getWidth(), mFgBitmap.getHeight(), mFgMatrix, true);
- }
- }
PopupWindow的布局popwindow.xml
注意3个LinearLayout里必须设置clickable和background,这样当点击上去的时候才会有点击效果。
android:clickable="true"
android:background="@drawable/state_btn_pressed"
- <?xml version="1.0" encoding="utf-8"?>
- <LinearLayout
- xmlns:android="http://schemas.android.com/apk/res/android"
- android:layout_width="fill_parent"
- android:layout_height="wrap_content"
- android:orientation="horizontal"
- android:id="@+id/layout_main"
- >
- <LinearLayout android:layout_width="fill_parent"
- android:layout_height="wrap_content"
- android:orientation="vertical"
- android:gravity="center_horizontal"
- android:clickable="true"
- android:background="@drawable/state_btn_pressed"
- android:layout_weight="1"
- android:id="@+id/btn_0"
- >
- <ImageView android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:scaleType="fitCenter"
- android:src="@drawable/ic_call"
- >
- </ImageView>
- <TextView android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:textColor="#000000"
- android:textSize="18px"
- android:text="电话">

- <LinearLayout android:layout_width="fill_parent"

- android:id="@+id/btn_1"
- >
- <ImageView android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:scaleType="fitCenter"
- android:src="@drawable/ic_home"
- >
- </ImageView>
- <TextView android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:textColor="#000"
- android:textSize="18px"
- android:text="空间">

- </LinearLayout>
- <LinearLayout android:layout_width="fill_parent"

- android:textColor="#000"
- android:textSize="18px"
- android:text="短信"
- >
- </TextView>
- </LinearLayout>
- </LinearLayout>
state_btn_pressed.xml,点击的效果:
- <?xml version="1.0" encoding="utf-8"?>
- <selector xmlns:android="http://schemas.android.com/apk/res/android">
- <item android:state_pressed="true"
- android:drawable="@drawable/bg_btn_pressed"
- android:padding="0dp"/>
- </selector>
Android 模仿迅雷的 PopupWindow 出现/消失动画
出现:
- <?xml version="1.0" encoding="utf-8"?>
- <set xmlns:android="http://schemas.android.com/apk/res/android">
- <scale android:fromXScale="0.6" android:toXScale="1.1"
- android:fromYScale="0.6" android:toYScale="1.1" android:pivotX="50%"
- android:pivotY="50%" android:duration="200" />
- <scale android:fromXScale="1.0" android:toXScale="0.91"
- android:fromYScale="1.0" android:toYScale="0.91" android:pivotX="50%"
- android:pivotY="50%" android:duration="400" android:delay="200" />
- <alpha android:interpolator="@android:anim/linear_interpolator"
- android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="400" />
- </set>
消失:
- <?xml version="1.0" encoding="utf-8"?>
- <set xmlns:android="http://schemas.android.com/apk/res/android">
- <scale android:fromXScale="1.0" android:toXScale="1.25"
- android:fromYScale="1.0" android:toYScale="1.25" android:pivotX="50%"
- android:pivotY="50%" android:duration="200" />
- <scale android:fromXScale="1.0" android:toXScale="0.48"
- android:fromYScale="1.0" android:toYScale="0.48" android:pivotX="50%"
- android:pivotY="50%" android:duration="400" android:delay="200" />
- <alpha android:interpolator="@android:anim/linear_interpolator"
- android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="400" />
- </set>
最后用下面的 XML 封装:
- <?xml version="1.0" encoding="utf-8"?>
- <resources>
- <style name="PopupAnimation" parent="android:Animation"
- mce_bogus="1">
- <item name="android:windowEnterAnimation">@anim/anim_dialog_show</item>
- <item name="android:windowExitAnimation">@anim/anim_dialog_hide</item>
- </style>
- </resources>
