自定义PopupWindowFromBottom
1 public class PopupWindowFromBottom extends PopupWindow { 2 3 4 public PopupWindowFromBottom(Context context, final View view) { 5 super(context); 6 LayoutInflater inflater = (LayoutInflater) context 7 .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 8 9 //设置按钮监听 10 //设置SelectPicPopupWindow的View 11 this.setContentView(view); 12 //设置SelectPicPopupWindow弹出窗体的宽 13 this.setWidth(LayoutParams.FILL_PARENT); 14 //设置SelectPicPopupWindow弹出窗体的高 15 this.setHeight(LayoutParams.WRAP_CONTENT); 16 //设置SelectPicPopupWindow弹出窗体可点击 17 this.setFocusable(true); 18 //设置SelectPicPopupWindow弹出窗体动画效果 19 this.setAnimationStyle(R.style.PopupAnimation); 20 //实例化一个ColorDrawable颜色为半透明 21 ColorDrawable dw = new ColorDrawable(0xb0000000); 22 //设置SelectPicPopupWindow弹出窗体的背景 23 this.setBackgroundDrawable(dw); 24 //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 25 view.setOnTouchListener(new OnTouchListener() { 26 27 public boolean onTouch(View v, MotionEvent event) { 28 29 int height = view.findViewById(R.id.picker_cancel).getTop(); 30 int y=(int) event.getY(); 31 if(event.getAction()==MotionEvent.ACTION_UP){ 32 if(y<height){ 33 dismiss(); 34 } 35 } 36 return true; 37 } 38 }); 39 40 } 41 42 }
涉及到了动画
push_bottom_in.xml <?xml version="1.0" encoding="utf-8"?> <!-- 上下滑入式 --> <set xmlns:android="http://schemas.android.com/apk/res/android" > <translate android:duration="200" android:fromYDelta="100%p" android:toYDelta="0" /> <alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="200" /> </set>
push_bottom_out.xml <?xml version="1.0" encoding="utf-8"?> <!-- 上下滑入式 --> <set xmlns:android="http://schemas.android.com/apk/res/android" > <translate android:duration="200" android:fromYDelta="0" android:toYDelta="50%p" /> <alpha android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="200" /> </set>
style.xml
1 <style name="PopupAnimation" parent="android:Animation"> 2 <item name="android:windowEnterAnimation">@anim/push_bottom_in</item> 3 <item name="android:windowExitAnimation">@anim/push_bottom_out</item> 4 </style>
使用了
if(!menuWindow.isShowing()){ menuWindow.showAtLocation(mParentView, Gravity.BOTTOM | Gravity.CENTER_HORIZONTAL, 0, 0); //设置layout在PopupWindow中显示的位置 }
