自定义弹窗控件

public class UpPopupWindow extends PopupWindow {

private Button takePhotoBtn, pickPhotoBtn, cancelBtn;
private View mMenuView;

@SuppressLint("InflateParams")
public UpPopupWindow(Context context, OnClickListener itemsOnClick) {
super(context);
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mMenuView = inflater.inflate(R.layout.layout_select_avatar, null);
takePhotoBtn = (Button) mMenuView.findViewById(R.id.text_choose_from_album);
pickPhotoBtn = (Button) mMenuView.findViewById(R.id.text_capture_image);
cancelBtn = (Button) mMenuView.findViewById(R.id.text_cancle);
// 设置按钮监听
cancelBtn.setOnClickListener(itemsOnClick);
pickPhotoBtn.setOnClickListener(itemsOnClick);
takePhotoBtn.setOnClickListener(itemsOnClick);

// 设置SelectPicPopupWindow的View
this.setContentView(mMenuView);
// 设置SelectPicPopupWindow弹出窗体的宽
this.setWidth(LayoutParams.MATCH_PARENT);
// 设置SelectPicPopupWindow弹出窗体的高
this.setHeight(LayoutParams.MATCH_PARENT);
// 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.UpPopupAnimation);
// 实例化一个ColorDrawable颜色为半透明
ColorDrawable dw = new ColorDrawable(0x80000000);
// 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
mMenuView.setOnTouchListener(new OnTouchListener() {

@Override
@SuppressLint("ClickableViewAccessibility")
public boolean onTouch(View v, MotionEvent event) {

int height = mMenuView.findViewById(R.id.pop_layout).getTop();
int y = (int) event.getY();
if (event.getAction() == MotionEvent.ACTION_UP) {
if (y < height) {
dismiss();
}
}
return true;
}
});

}

}

在界面Activity里设置

private UpPopupWindow popupWindow;

在点击事件里设置

popupWindow = new UpPopupWindow(getActivity(), selectImageClick);

popupWindow.showAtLocation(getActivity().findViewById(R.id.layout_userinfos), Gravity.BOTTOM | Gravity.CENTER_HORIZONTAL, 0, 0);//第一个参数是住布局总控件

弹出框的点击处理

private OnClickListener selectImageClick = new OnClickListener() {
@Override
public void onClick(View v) {
popupWindow.dismiss();
switch (v.getId()) {
case R.id.text_choose_from_album:

break;
case R.id.text_capture_image:

break;
case R.id.text_cancle:
break;
}
}
};
