如何以编程方式/动态更改TabHost的标签

Question

我有一个tabhost创建

  this.tabHost = getTabHost();

     // Resusable TabSpec for each tab
    Intent intent;  // Reusable Intent for each tab

    // Create an Intent to launch the first Activity for the tab (to be reused)
    intent = new Intent().setClass(this, FirstGroup.class);

    // Initialize a TabSpec for the first tab and add it to the TabHost
    spec1 = tabHost.newTabSpec("FirstGroup").setIndicator("Regionlar",
            getResources().getDrawable(R.drawable.region2)) // Replace null with R.drawable.your_icon to set tab icon
                    .setContent(intent);
    tabHost.addTab(spec1);

我想以编程方式更改tabhost的标签:"Regionlar"到"newMenuTabbar".我找不到任何例子.谢谢你的关注.

编辑:我想从"Mənzərələr"=>"secondTabitem"改变第二个tabitem的标签

intent = new Intent().setClass(this,FirstGroup.class);

    // Initialize a TabSpec for the first tab and add it to the TabHost
    spec1 = tabHost.newTabSpec("FirstGroup").setIndicator("Regionlar",
            getResources().getDrawable(R.drawable.region2)) // Replace null with R.drawable.your_icon to set tab icon
                    .setContent(intent);
    tabHost.addTab(spec1);

        // Create an Intent to launch an Activity for the tab (to be reused)
    intent = new Intent().setClass(this, SecondActivityGroup.class);
    spec2 = tabHost.newTabSpec("SecondActivityGroup").setIndicator("M?nz?r?l?r",
            getResources().getDrawable(R.drawable.img_gallery_icon)) // Replace null with R.drawable.your_icon to set tab icon
                    .setContent(intent);
    tabHost.addTab(spec2);

Answer 1

试试这个:

final TextView label = (TextView) tabHost.getTabWidget().findViewById(android.R.id.title);
label .setText(YOUR NEW LABEL);

希望它会有所帮助.
