如何完成一个Android应用程序？ [英] How to finish an android application?

问题描述

我需要完成一个Android应用程序。对于我写

I need to finish an android application. For that i wrote

@Override
public void onBackPressed() {
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setMessage("Are you sure You want to exit")
        .setCancelable(false)
        .setPositiveButton("YES"),
        new DialogInterface.OnClickListener() {
            // On
            // clicking
            // "Yes"
            // button

            public void onClick(DialogInterface dialog,int id) {
                System.out.println(" onClick ");
                closeApplication(); // Close Application method called
            }
        })
        .setNegativeButton("NO"),
        new DialogInterface.OnClickListener() {
            // On
            // clicking
            // "No"
            // button
            public void onClick(DialogInterface dialog,int id) {
                dialog.cancel();
            }
        });

        AlertDialog alert = builder.create();
        alert.show();
    }

    private void closeApplication() {
        System.out.println("closeApplication ");
        this.finish();
    }
}

但是，如果所有行为都没有在应用程序完成后，当我试图退出该活动已完成第一和应用程序不退出应用程序..我试过2次退出该应用程序...我怎么能完成所有的当我需要在应用程序中的活动，退出...或者是有没有什么办法来完成整个应用程序

But if any activity is not finished in the application, when i tried to exit the application that activity is finished first and the application is not exiting.. i tried 2 times to exit this application... How i can finish all the activities in an application when i need to exit... or is there any way to finish the entire application

推荐答案

每当你开始一个新的活动中使用

whenever you are starting a new activity use

myintent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(myintent);

和清单文件提到，活性

<activity android:name=".<Activity Name>" >
        <intent-filter>
        <action android:name="android.intent.action.VIEW"/>
     <category android:name="android.intent.category.DEFAULT" />
     </intent-filter>
       </activity>
