Java代码

tHost = this.getTabHost();

tHost = this.getTabHost();

Java代码

public static final String Tab1 = "Tab1";

public static final String Tab2 = "Tab2";

public static final String Tab3 = "Tab3";

public static final String Tab4 = "Tab4";

public static final String Tab5 = "Tab5";

tHost.addTab(tHost.newTabSpec(Tab1).setIndicator("Tab 1", getResources().getDrawable(R.drawable.icon)).setContent(R.id.view1));

tHost.addTab(tHost.newTabSpec(Tab2).setIndicator("Tab 2",
