我的应用程序中有一个警报，每 10 分钟通知我一次。它工作正常，但是每次警报通知我时，我的应用程序名称都会在屏幕中间显示为一个框，并且在按下返回按钮之前我无法按下任何东西。真的很奇怪！
这是我的代码：
// Alert Code
final AlertDialog alertDialog = new AlertDialog.Builder(this).create();
alertDialog.setTitle("Confirmation");
alertDialog.setMessage("Are you sure you want to send this report?");
run(gotDataS);
// Timer Code
pendingIntent = PendingIntent.getService(CreateNewForm_3.this, 0,
new Intent(NewForm_3.this, MyAlarmService.class), 0);
Send.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
alertDialog.setButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int which) {
Toast.makeText(NewForm_3.this, "Sent", 0)
.show();
long firstTime = SystemClock.elapsedRealtime();
am = (AlarmManager) getSystemService(ALARM_SERVICE);
am.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
firstTime + 10 * 1000, 30 * 1000, pendingIntent);
// firstTime Will be the current_time + ( 10 * 60 * 1000) =)
// 10* 1000 will be (10 * 60 * 1000)
new Handler().postDelayed(new Runnable() {
public void run() {
bCancel.performClick();
}
}, (30 * 1000));
// ( 30 * 1000) will be firstTime + ( 2- duration)
Intent toRecentCases = new Intent(CreateNewForm_3.this,
LMPActivity.class);
startActivity(toRecentCases);
}
});
alertDialog.setButton2("No",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int which) {
// Here you can add functions
}
});
alertDialog.setIcon(android.R.drawable.ic_dialog_alert);
alertDialog.show();
}
});
bCancel.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
am.cancel(pendingIntent);
}
});
//For Notification -3-
final AlertDialog alertDialog3 = new AlertDialog.Builder(this).create();
alertDialog3.setTitle("Confirmation");
alertDialog3.setMessage("Are you sure you want to quite?");
// Press cancel button it will move user to actvity p
Cancelb.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
alertDialog3.setButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int which) {
Intent toRecentCases = new Intent(NewForm_3.this,
LMPActivity.class);
startActivity(toRecentCases);
}
});
alertDialog3.setButton2("No",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int which) {
// Doing nothing!
}
});
alertDialog3.setIcon(android.R.drawable.ic_dialog_alert);
alertDialog3.show();
}
});
}
这是显示对话框活动
public class ShowingDialog extends Activity {
boolean b;
String CancelMsg;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
//For Notification -1-
final AlertDialog alertDialog = new AlertDialog.Builder(this).create();
alertDialog.setTitle("Confirmation");
alertDialog.setMessage("Do you really want it?");
// For Notification -2-
final AlertDialog alertDialog2 = new AlertDialog.Builder(this).create();
alertDialog2.setTitle("Confirmation");
alertDialog2.setMessage("Are you sure you want it?");
alertDialog.setButton("yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
Intent intent= new Intent(ShowingDialog.this,MyPage.class);
startActivity(intent);
;
}
});
alertDialog.setButton2("no",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int which) {
alertDialog2.setButton("yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// Here you can add functions
// Sending a Message to server that the plaintiff found the case
// For Sending SMS with cancel Request
// Getting Case_ID + putting it inside CancelMsg
CancelMsg = "Case_ID cancel";
if (!b) {
try {
sendSMS("5556", CancelMsg);
Toast.makeText(ShowingDialog.this, "Sent", Toast.LENGTH_LONG)
.show();
} catch (Exception e) {
// TODO Auto-generated catch block
Toast.makeText(ShowingDialog.this, e.getMessage(),
Toast.LENGTH_LONG).show();
}
}
}
});
alertDialog2.setButton2("no", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// Here you can add functions
// Do nothing
}
});
alertDialog2.setIcon(android.R.drawable.ic_dialog_alert);
alertDialog2.show();
}
});
alertDialog.setIcon(android.R.drawable.ic_dialog_alert);
alertDialog.show();
}
public void sendSMS(String number, String msg) throws Exception {
if (!b) {
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(number, null, msg, null, null);
}
b = true;
}
}
在清单中：
<activity
android:name=".ShowingDialog"
android:theme="@android:style/Theme.Dialog" />
