[Android]最简单实现一键关闭APP

直接上代码

Manifest

<activity
    
    android:launchMode="singleTask">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />

        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

Activity

public class CloseActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_close);

        startActivity(new Intent(this, SplashActivity.class));
        //startActivity(new Intent(this, LoginActivity.class));
    }

    @Override
    protected void onNewIntent(Intent intent) {
        super.onNewIntent(intent);
        finish();
    }
}

使用

startActivity(new Intent(this, CloseActivity.class))

BUG

启动页为singleTask时,HOME键回到桌面再次点击图标会重启应用,最近列表回到应用无影响.

ps.有类似推送新开栈自己处理
