Tabhost窃取焦点

标签： android-tabhost android-scrollview tabwidget

我的应用程序底部有一个RadioGroup由4个RadioButtons组成。当我按下按钮时，它会启动一个活动。已经启动的活动是一个scrollview，其中有一个TabHost TabWidget ViewPager。当我第一次启动应用程序并使用TabHost活动单击RadioButton时，焦点位于顶部。但是，当我点击另一个RadioButton并返回TabHost活动时。焦点位于viewPager的底部。 

public class DActivity extends FragmentActivity implements TabHost.OnTabChangeListener, ViewPager.OnPageChangeListener {
private TabsPagerAdapter mAdapter;
private ViewPager mViewPager;
private TabHost mTabHost;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.me_profile);

    mViewPager = (ViewPager) findViewById(R.id.viewpager);

    // Tab Initialization
    initialiseTabHost();
    mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
    // Fragments and ViewPager Initialization


    mViewPager.setAdapter(mAdapter);

    View v = this.mTabHost.getTabWidget().getChildAt(0);
    v.setBackgroundColor(Color.parseColor("#fff0f0f0"));


    TextView tv = (TextView) this.mTabHost.getTabWidget().getChildAt(0).findViewById(android.R.id.title);
    tv.setTextColor(Color.parseColor("#fa4e52"));

    View v2 = this.mTabHost.getTabWidget().getChildAt(1);
    v2.setBackgroundColor(Color.parseColor("#fff0f0f0"));

    TextView tv2 = (TextView) this.mTabHost.getTabWidget().getChildAt(1).findViewById(android.R.id.title);
    tv2.setTextColor(Color.parseColor("#b3b3b3"));

    mViewPager.setOnPageChangeListener(DActivity.this);
}

// Method to add a TabHost
private static void AddTab(DActivity activity, final TabHost tabHost, TabHost.TabSpec tabSpec) {
    tabSpec.setContent(new MyTabFactory(activity));
    tabHost.addTab(tabSpec);

}

// Manages the Tab changes, synchronizing it with Pages
public void onTabChanged(String tag) {
    int pos = this.mTabHost.getCurrentTab();
    this.mViewPager.setCurrentItem(pos);
    for (int i = 0; i < this.mTabHost.getTabWidget().getChildCount(); i++) {
        this.mTabHost.getTabWidget().getChildAt(i).setBackgroundColor(Color.parseColor("#fff0f0f0")); // unselected
        TextView tv = (TextView) this.mTabHost.getTabWidget().getChildAt(i).findViewById(android.R.id.title); //Unselected Tabs
        tv.setTextColor(Color.parseColor("#b3b3b3"));
    }

    this.mTabHost.getTabWidget().getChildAt(this.mTabHost.getCurrentTab()).setBackgroundColor(Color.parseColor("#fff0f0f0")); // selected
    TextView tv = (TextView) this.mTabHost.getCurrentTabView().findViewById(android.R.id.title); //for Selected Tab
    tv.setTextColor(Color.parseColor("#fa4e52"));



}


@Override
public void onPageScrollStateChanged(int arg0) {
}

// Manages the Page changes, synchronizing it with Tabs
@Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
    int pos = this.mViewPager.getCurrentItem();
    this.mTabHost.setCurrentTab(pos);
}

@Override
public void onPageSelected(int arg0) {
}


// Tabs Creation
private void initialiseTabHost() {
    mTabHost = (TabHost) findViewById(android.R.id.tabhost);
    mTabHost.setup();

    // TODO Put here your Tabs
    DActivity.AddTab(this, this.mTabHost, this.mTabHost.newTabSpec("MOST CHAMPION").setIndicator("MOST CHAMPION"));
    DActivity.AddTab(this, this.mTabHost, this.mTabHost.newTabSpec("RECENT MATCH").setIndicator("RECENT MATCH"));


    mTabHost.setOnTabChangedListener(this);
}

}
