使用android中的多个选项卡调整tabhost？
我有一个tabhost，共有6个标签。当我在平板电脑上打开这个应用程但是当我在较小的设备中打开它时，标签会如下所示变得拥挤。
我希望这些标签看起来像这样。
可能是滚动视图会这样做。但我无法做到。我尝试了水平滚动视图，但随后一个选项卡的宽度超出了屏幕限制。用户必须继续滚动才能转到第二个标签页。
这是我的xml代码。
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_above="@android:id/tabs"
android:layout_weight="1"
android:layout_height="fill_parent"/>
<TabWidget
android:id="@android:id/tabs"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/subbgg" />
</LinearLayout>
</TabHost>
这是我的java代码。
public class Register extends TabActivity {
//TabHost tabHost;
public static TabHost tabHost;
// Button logout;
@Override
public void onBackPressed() {
//Register.this.finish();
//super.onBackPressed();
}
public Register() {
}
public Register(int tabindex){
}
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.register);
if( getIntent().getBooleanExtra("Exit me", false)){
finish();
return; // add this to prevent from doing unnecessary stuffs

根据您的尺寸将其添加到您的java文件中。
tabHost.getTabWidget().getChildAt(0).getLayoutParams().width = 50;
答案 1 :(得分：1)
我通过动态获取android屏幕宽度并减少tab小部件的文本大小来实现这一点
int width = WindowHeighAndWidth.getScreenWidth（TabHostAct.this）;
if(width<542){
titleTv.setTextSize(12.0f);
titleSaleTV.setTextSize(12.0f);
titlePurchTV.setTextSize(12.0f);
titlePayTV.setTextSize(12.0f);
titleStockTV.setTextSize(12.0f);
}
这里是WindowHeightAndWidth类：
public class WindowHeighAndWidth {public static int getScreenWidth(Context context){
DisplayMetrics dm = new DisplayMetrics();
WindowManager windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
windowManager.getDefaultDisplay().getMetrics(dm);
int widthInPx = dm.widthPixels;
return widthInPx;
}
}
titlePurchTv是一个TextView，我从布局中获取并在`
上设置spec = tabHost.newTabSpec("home"); // Create a new TabSpec using tab host
// spec.setIndicator("Sale"); // set the “HOME” as an indicator
spec.setIndicator(homeView); //here you can set a layout
我希望它会对你有所帮助。如有任何问题，请发表评论
