Due to this, the image in the title bar is visible in all 3 tabs. My requirement is to set a different image to title bar for each activity. I followed this to set image to title bar. But when i am going to do the same thing to each activity, getting android.util.AndroidRuntimeException: You cannot combine custom titles with other title features this error and application is terminated.

推荐答案

您好，您不能使用自定义标题从嵌套在该活动的特征 TabHost 。

Hello You cannot use Custom Title feature from activities that are nested in TabHost.

也就是说，如果你是从申请自定义标题的活动A 和 b活动的嵌套在 TabActivity Android将引发异常，你提到的上方。

That is if you are requesting Custom Title from Activity A and Activity B which are nested in TabActivity Android will throw the exception you mentioned above.

解决这个问题是让TabActivity要求自定义标题。而从活动A和活动B的内部改变TabActivity的自定义标题内容。

Work around to this issue is to let TabActivity request custom title. And change content of Custom Title of TabActivity from inside the Activity A and Activity B.

另一个秘诀，我可以给你的是覆盖活动A和活动B的 onResume（）呼吁改变TabActivity自定义标题。

Another tip I can give you is override the onResume() call of Activity A and Activity B to change the TabActivity custom title.

编辑：样品code

有关你的选项卡的活动。

For your tab activity

public class TabLayoutDemo extends TabActivity {

//CREATING A PUBLIC STATIC VARIABLE
public static TabLayoutDemoInstance myTabLayoutDemo;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
    setContentView(R.layout.main);

    TabLayoutDemo.TabLayoutDemoInstance=this;//STORING 

    //COMMENTING SET FEATURE IN TAB
    //getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.my_title);
//REST CODE REMAINS SAME

现在为您的活动A和B

Now for your Activity A and B

public class ActivityA extends Activity{
//LOST MORE CODE ABOVE
@Override
protected void onResume() {
    super.onResume();
//SET FEATURE FROM INSIDE ACTIVITY
    TabLayoutDemo.TabLayoutDemoInstance.getWindow().
           setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.my_title);
}

}

复制上面指定的B来说ActivityA的简历。

Copy on resume of ActivityA specified above for B as well.

提示：你可以改变使用这个从每个活动更改标题布局

Tip: you can change change the title layout from each activity using this.
