Question

我正在使用以下代码在tabHost上添加标签但在第一行到最后一行崩溃，spec.setContent（intent）。调试器说不是太多。谢谢。

来自Registrat，

Intent intentIOS = new Intent(Registrat.this, TabBar_Activity.class);
Bundle bundle = new Bundle();
bundle.putString("idusuari", idusuari);
String appid = null;

来自TabBar_Activity的

，

private void setTabs(String numTabs){

        addTab(tab1name, "tab1", myTab1.class);
        addTab(tab2name, "tab2", myTab2.class);
}

private void addTab(String labelId, String imageName, Class<?> c)
    {
      TabHost tabHost = getTabHost();
          Intent intent = new Intent(this, c);
          TabHost.TabSpec spec = tabHost.newTabSpec("tab" + labelId); 

          View tabIndicator = LayoutInflater.from(this).inflate(R.layout.tab_indicator, getTabWidget(), false);
          TextView title = (TextView) tabIndicator.findViewById(R.id.title);
          title.setText(labelId);    

          spec.setIndicator(tabIndicator);
          spec.setContent(intent);
          tabHost.addTab(spec);
    }

要设置标签，我正在使用以下代码，它可以正常工作。

TabHost tabHost = getTabHost();

// Tab for Photos
TabSpec photospec = tabHost.newTabSpec("Photos");
// setting Title and Icon for the Tab
photospec.setIndicator("Photos", getResources().getDrawable(R.drawable.icon_photos_tab));
Intent photosIntent = new Intent(this, PhotosActivity.class);
photospec.setContent(photosIntent);

// Tab for Songs
TabSpec songspec = tabHost.newTabSpec("Songs");
songspec.setIndicator("Songs", getResources().getDrawable(R.drawable.icon_songs_tab));
Intent songsIntent = new Intent(this, SongsActivity.class);
songspec.setContent(songsIntent);
 // Adding all TabSpec to TabHost
tabHost.addTab(photospec); // Adding photos tab
tabHost.addTab(songspec); // Adding songs tab

android将tab添加到tabhost
