Android让App彻底退出的实现方法。
1)先在AndroidManifest.xml文件中添加<uses-permission android:name="android.permission.RESTART_PACKAGES" />
2)然后在自己的Activity重写onKeyDown()方法。具体实现如下：
- @Override
- public boolean onKeyDown(int keyCode, KeyEvent event) {
- if(keyCode==KeyEvent.KEYCODE_BACK&&event.getRepeatCount()==0){
- AlertDialog.Builder alertbBuilder=new AlertDialog.Builder(this);
- alertbBuilder.setTitle("真的要离开？").setMessage("你确定要离开？").setPositiveButton("确定", new DialogInterface.OnClickListener() {
- @Override
- public void onClick(DialogInterface dialog, int which) {
- //结束这个Activity
- int nPid = android.os.Process.myPid();
- android.os.Process.killProcess(nPid);
- }
- }).setNegativeButton("取消", new DialogInterface.OnClickListener() {
- @Override
- public void onClick(DialogInterface dialog, int which) {
- dialog.cancel();
- }
- }).create();
- alertbBuilder.show();
- }
- return true;
- }
