我对警报对话框有一些问题...我如何调用 alert.show(); 在第二课中调用警报对话框？
我需要显示 alertdialog onReceive 方法，但我不能这样做......
有人可以帮我吗？
ps对不起我的英语..;|
主类：
public class Main extends Activity {
...
public void onTimeSet(TimePicker view, int hour, int minute) {
...
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("ALARM");
builder.setMessage("Wstajesz czy dalej drzemiesz ?!");
builder.setPositiveButton("Wstaje...", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// Do do my action here
dialog.dismiss();
}
});
builder.setNegativeButton("Spie!", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// I do not need any action here you might
dialog.dismiss();
}
});
AlertDialog alert = builder.create();
alert.show();
....
}
二等：
public class Second extends BroadcastReceiver {
@Override
public void onReceive(Context k1, Intent k2) {
/*
--> here i want to call an alert using: alert.show(); It's possible ?
*/
}
}
