¿Podemos establecer una imagen de fondo en pestañas?

El siguiente código funcionó para mí:

tabHost.getTabWidget().setBackgroundResource(R.drawable.tabhost_bg); 

prueba esto

  getTabHost().addTab(getTabHost().newTabSpec("A") //set the tab name .setIndicator("A") //Add additional flags to the intent (or with existing flags value). .setContent(new Intent(this, A.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP))); //for creating tab we need to pass tabSpec and tab name to setIndicator and pass intent to its //setContent to Tab Activity predefined method getTabHost then it will create tab getTabHost().addTab(getTabHost().newTabSpec("B") //set the tab name .setIndicator("B") //Add additional flags to the intent (or with existing flags value). .setContent(new Intent(this,B.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)) ); getTabHost().addTab(getTabHost().newTabSpec("C") //set the tab name .setIndicator("C") //Add additional flags to the intent (or with existing flags value). .setContent(new Intent(this,C.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)) ); getTabHost().getTabWidget().getChildAt(0).setBackgroundResource(R.drawable.a); getTabHost().getTabWidget().getChildAt(1).setBackgroundResource(R.drawable.b); getTabHost().getTabWidget().getChildAt(2).setBackgroundResource(R.drawable.c); 

 TabSpec generalTab = mTabHost.newTabSpec("general"); generalTab.setIndicator("General", getResources().getDrawable(android.R.drawable.ic_menu_preferences)).setContent(R.id.tabGeneral); 

He utilizado predeterminado android drawable u puede utilizar lo que quieras

Para configurar el fondo de tabhost

 this.mTabHost = (TabHost)this.findViewById(R.id.tabHost); this.mTabHost.setBackgroundResource(R.drawable.back);
