我是android.nd的新手现在我正在开发一个应用程序，其中我使用了标签并将其扩展为片段活动...每个标签都是片段。我有一个标签，其中我有一个列表视图如果我点击我打开了一个详细的视图...我在detailview上添加了一个按钮...当用户点击该按钮时，API ping完成，并且在onpostexecute（）上应用应该转到第二个选项卡......但它不起作用..现在，我正在将它导航到..碎片活动，即对于第一个选项卡的默认活动，但是要求是第二个选项卡。
的DetailView ：
if(val.contains("success"))
{
Intent intent = new Intent(getApplicationContext(),LiveSeedsActivity.class);
intent.putExtra("login", val);
Log.d("srafasfddddddddddddd",String.valueOf(val));
startActivity(intent);
}else{
Toast.makeText(getApplicationContext(),"Insufficient Seeds", Toast.LENGTH_LONG).show();
}
