Android Studio: @Override "Annotations are not allowed here"
提问by
I want to implement the ...
我想实施...
@Override
public void onBackPressed() {
}
However, I get an error message saying, "Annotations are not allowed here". I need this method to be implemented here. Is there an alternative?
但是，我收到一条错误消息，说“此处不允许使用注释”。我需要在这里实现这个方法。有替代方案吗？
public class supbreh extends Appbreh
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_intent_breh);
if (myBundle != null) {
String name = myBundle.getString("workout");
ShowDetails(name);
}
}
private void ShowAbDetails(String mName) {
if(mName.equals("abs1")){
@Override
public void onBackPressed() { //"Not Allowed here"
}
}

void onBackPressed ()
Called when the activity has detected the user's press of the back key. The default implementation simply finishes the current activity, but you can override this to do whatever you want.
当活动检测到用户按下后退键时调用。默认实现只是完成当前活动，但您可以覆盖它以执行任何您想要的操作。
In here you can't declare this method inside another method .
在这里你不能在另一个方法中声明这个方法。
Only override it in that one Activity
只在那个 Activity 中覆盖它
@Override
public void onBackPressed()
{
super.onBackPressed();
}
FYI
供参考
@Override
public void onBackPressed() {
Intent intent = new Intent(IndividualAbsWorkout.this, IndividualAbsWorkout.class);
startActivity(intent);
}

You can override onBackPressed as normal and call the method in ShowAbDetails() method like below.
您可以正常覆盖 onBackPressed 并调用 ShowAbDetails() 方法中的方法，如下所示。
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_intent_breh);
if (myBundle != null) {
String name = myBundle.getString("workout");
ShowDetails(name);
}
}
private void ShowAbDetails(String mName) {
if(mName.equals("abs1")){
onBackPressed();
}
}
@Override
public void onBackPressed() {
// your logic here
}
