try to change this segment:
尝试更改此段：
tab1.setIndicator("Tab1");
tab1.setContent(new Intent(this,Tab1Activity.class));
tab1.setIndicator("Tab2");
tab1.setContent(new Intent(this,Tab2Activity.class));
tab1.setIndicator("Tab3");
tab1.setContent(new Intent(this,Tab3Activity.class));
with the below one .... like this:
与下面的....像这样：
tab1.setIndicator("Tab1");
tab1.setContent(new Intent(this,Tab1Activity.class));
--> tab2.setIndicator("Tab2");
--> tab2.setContent(new Intent(this,Tab2Activity.class));
--> tab3.setIndicator("Tab3");
--> tab3.setContent(new Intent(this,Tab3Activity.class));
The error is because your are not using tab2 or tab3 and using tab1 repeatedly.
错误是因为您没有使用 tab2 或 tab3 并重复使用 tab1。
Hope this helps.
希望这可以帮助。
