知晓当前在哪个活动
创建一个BaseActivity 类继承Activity 在onCreate 中输出类名
代码语言:javascript复制public class BaseActivity extends AppCompatActivity {
private static final String TAG = "BaseActivity";
@Override
public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState) {
super.onCreate(savedInstanceState, persistentState);
Log.d(TAG, getClass().getSimpleName());
}
}
随时随地退出程序
新建一个ActivityCollector 作为活动管理器
代码语言:javascript复制public class ActivityCollector {
public static List<Activity> activities = new ArrayList<>();
public static void addActivity(Activity activity) {
activities.add(activity);
}
public static void remoteActivity(Activity activity) {
activities.remove(activity);
}
// 销毁所有Activity
public static void finishAll() {
for (Activity activity : activities) {
if (!activity.isFinishing()) {
activity.finish();
}
}
}
}
在BaseActivity
代码语言:javascript复制public class BaseActivity extends AppCompatActivity {
private static final String TAG = "BaseActivity";
@Override
public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState) {
super.onCreate(savedInstanceState, persistentState);
Log.d(TAG, getClass().getSimpleName());
ActivityCollector.addActivity(this);
}
@Override
protected void onDestroy() {
super.onDestroy();
ActivityCollector.remoteActivity(this);
}
}
在什么时候退出程序
只需要调用ActivityCollector.finishAll()方法 可以在销毁所有活动后加上杀掉进程代码
代码语言:javascript复制ActivityCollector.finishAll();
android.os.Process.killProcess(android.os.Process.myPid());
