android popupwindow 等待对话框 选择dialog

让用户等待执行完。 

import android.widget.PopupWindow;


//新建实例
final PopupWindow popupWindow = new PopupWindow();




//显示
popupWindow.setOutsideTouchable(false);
popupWindow.setFocusable(false);//点击区域外不会消失，点击返回会执行back事件
popupWindow.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT);
popupWindow.setWidth(ViewGroup.LayoutParams.WRAP_CONTENT);
View view = LayoutInflater.from(MainActivity.this).inflate(R.layout.popup,null);
popupWindow.setContentView(view);
popupWindow.showAtLocation(getWindow().getDecorView(), Gravity.CENTER,0,0);


//消失
popupWindow.dismiss();

 popup.xml

另外常用 

//用户选择对话框
new alertDialog.Builder(this)
.setTitle("提示")
.setMessage("是否人为结束,重新开始?")
.setPositiveButton("确定", new DialogInterface.onClickListener() {

		@Override
		public void onClick(DialogInterface dialog, int which) {
			//点确定要执行的内容
		}
})
.setNegativeButton("取消", null).show();
