我正在制作一个通知用户的简单闹钟应用.我想制作一个警报框,让用户可以选择在警报响起时关闭警报.我能够制作警报框,但它只出现在应用程序中而不出现在应用程序之外.我知道该应用程序必须在后台运行.如果我需要显示更多代码或更具体,请询问.
I am making a simple alarm clock app that notifies the user. I want to make a alert box that gives the user the option to turn off the alarm when it goes off. I was able to make the alert box, but it only appears in the app not outside of the app. I understand the app has to be in the background running. If I need to show more code or be more specific, just ask please.
推荐答案
添加一行:
public void ShowDialog() {
final AlertDialog.Builder alertDialog = new AlertDialog.Builder(this);
alertDialog.setTitle("REMINDER!");
alertDialog.setMessage("Turn off alarm by pressing off");
alertDialog.setNegativeButton("Off", new DialogInterface.OnClickListener(){
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(getApplicationContext(), "OFF", Toast.LENGTH_SHORT).show();
}
});
alertDialog.show();
// line you have to add
alertDialog.getWindow().setType(WindowManager.LayoutParams.TYPE_TOAST);
}
立即检查.
