Selector with image and textview at the same time

Question

我知道如何为imageview做一个选择器以及如何为textView做一个选择器，现在我有一个tabwidget，其中包含选项卡，每个选项卡下面都有图像和文本视图，我的问题是如何更改图像视图的背景和颜色当用户单击选项卡时，将显示文本视图。

You have to use TabHost.TabSpec.setIndicator(View view) to define your own layout where you set your selectors. You can reuse tab_indicator.xml layout, can be found in platforms/android-xx/data/res/drawable .

excerpt:

mTabHost = (TabHost) findViewById(android.R.id.tabhost);

private View createTabView(CharSequence label, Drawable icon) {
    View tabIndicator = LayoutInflater.from(mContext).inflate(R.layout.tab_indicator, mTabHost.getTabWidget(), false);
    TextView tv = (TextView) tabIndicator.findViewById(R.id.title);
    tv.setText(label);
    ImageView iv = (ImageView) tabIndicator.findViewById(R.id.icon).
    iv.setDrawable(icon);
    return tabIndicator;
}

public void addTab(CharSequence label, Drawable icon) {
    View tabIndicator = createTabView(label, icon);
    TabHost.TabSpec tabSpec = mTabHost.newTabSpec(label.toString()).setIndicator(tabIndicator).setContent(...);
    mTabHost.addTab(tabSpec);
}
