popupwindow

1、定义

private PopupWindow pw;
private Button grzx_btn_camera, grzx_btn_gallery;

2、初始化设置

private void selectWay(){
  View myView = getLayoutInflater().inflate(R.layout.pop_grzx_photoway,null);
  grzx_btn_camera = (Button) myView.findViewById(R.id.grzx_btn_camera);
  grzx_btn_gallery = (Button) myView.findViewById(R.id.grzx_btn_gallery);
  mCheckBox = (CheckBox) myView.findViewById(R.id.checkbox);
  grzx_btn_camera.setOnClickListener(this);
  grzx_btn_gallery.setOnClickListener(this);
  pw = new PopupWindow(myView, LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT, true);
  pw.setTouchable(true);
  pw.setFocusable(true);// 使其聚集
  pw.setOutsideTouchable(true);// 设置允许在外点击消失
  pw.setBackgroundDrawable(getResources().getDrawable(R.drawable.bg_text_back));
  WindowManager.LayoutParams params = getWindow().getAttributes();
  params.alpha = 0.7f;
  getWindow().setAttributes(params);
  pw.setOnDismissListener(this);
  pw.showAtLocation(myView, Gravity.CENTER | Gravity.CENTER, 0, 0);
}

3、显示与取消

//执行展示
selectWay();
//判断取消
if (pw.isShowing()) {
  pw.dismiss();
 }
