Question

我正在开发一个应用程序，我必须在更改选项卡时更改一个选项卡的视图。我是按照OnTabChangedListener的方式进行的。我能够取代视图。但是，当我将标签更改为其他标签时，之前的视图仍然可以在后台显示？为什么会这样？在前面，将填充新视图，但如果我点击屏幕上任何前一个视图控件所在的位置，则会执行该功能。我没有得到问题所在。请帮帮我。谢谢！

public class FragmentTabs extends FragmentActivity implements OnTabChangeListener {

private FragmentTabHost mTabHost;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    this.requestWindowFeature(Window.FEATURE_NO_TITLE);

    setContentView(R.layout.fragment_tabs);

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

    mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent);

    mTabHost.setOnTabChangedListener(this);

    if (Database.getSharedObject(getApplicationContext()).getAppSettings().getListView() == 1) {
        mTabHost.addTab(mTabHost.newTabSpec("home").setIndicator("", getResources().getDrawable(R.drawable.home_tab)), HomeFragment.class, null);

    } else {
        mTabHost.addTab(mTabHost.newTabSpec("home").setIndicator("", getResources().getDrawable(R.drawable.home_tab)), CalendarViewFragment.class, null);
    }
    mTabHost.addTab(mTabHost.newTabSpec("groups").setIndicator("", getResources().getDrawable(R.drawable.groups_tab)), GroupFragment.class, null);
    mTabHost.addTab(mTabHost.newTabSpec("templates").setIndicator("", getResources().getDrawable(R.drawable.templates_tab)), TemplateFragment.class, null);
    mTabHost.addTab(mTabHost.newTabSpec("settings").setIndicator("", getResource
    mTabHost.getTabWidget().getChildAt(0).getLayoutParams().height = height;
    mTabHost.getTabWidget().getChildAt(1).getLayoutParams().height = height;
    mTabHost.getTabWidget().getChildAt(2).getLayoutParams().height = height;
    mTabHost.getTabWidget().getChildAt(3).getLayoutParams().height = height;
    // Database.getSharedObject(getApplicationContext());

    mTabHost.setCurrentTab(0);
}

@Override
protected void onResume() {
    super.onResume();

}

@Override
public void onTabChanged(String arg0) {

    mTabHost.getCurrentTabView().invalidate();

    if (mTabHost.getCurrentTab() == 0) {
        if (Database.getSharedObject(getApplicationContext()).getAppSettings().getListView() == 1) {

            HomeFragment homeFragment = new HomeFragment();
            mTabHost.getCurrentTabView().invalidate();
            getSupportFragmentManager().beginTransaction().replace(R.id.realtabcontent, homeFragment).addToBackStack(null).commit();
        } else {

            CalendarViewFragment calendarViewFragment = new CalendarViewFragment();
            mTabHost.getCurrentTabView().invalidate();
            getSupportFragmentManager().beginTransaction().replace(R.id.realtabcontent, calendarViewFragment).addToBackStack(null).commit();

        }

    }

}

}

将android:clickable="true"添加到新标签的根布局中。它将阻止点击事件通过后面的布局传递。

替换片段：上一个视图在后台保持活动状态？
