我使用一个自定义TabWidget来显示我的选项卡。当我第一次运行程序时,选项卡工作得非常好。一切看起来都很美。但是,当我重新加载程序时,根据logcat, onResume()方法在我的TabWidget上被调用,TabWidget只显示小部件的上半部分。下面是TabWidget的XML。
<?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" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="@android:id/tabs"/>
<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="55dp"
android:layout_alignParentBottom="true" />
</RelativeLayout>
</TabHost>
这是非常普通的香草的东西。改变layout_height没有帮助。
我目前没有实现onResume在我的TabWidget.java。但这里还是有代码。
public class TabWidget extends TabActivity {
private TabHost mTabHost;
private void setupTabHost() {
mTabHost = (TabHost) findViewById(android.R.id.tabhost);
mTabHost.setup();
}
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.tabs);
Resources res = getResources(); // Resource object to get Drawables
TabHost tabHost = (TabHost) findViewById(android.R.id.tabhost); // The
// activity
// TabHost
TabHost.TabSpec spec; // Resusable TabSpec for each tab
Intent intent; // Reusable Intent for each tab
setupTabHost();
// mTabHost.getTabWidget().setDividerDrawable(R.drawable.tab_divider);
// Dealer tab
Intent intentDealer = new Intent().setClass(this, DealerActivity.class);
int iconDealer = (R.drawable.ic_tab_dealer);
setupTab("Dealer", intentDealer, iconDealer);
// Department tab
Intent intentDept = new Intent().setClass(this, DeptActivity.class);
int iconDept = R.drawable.ic_tab_dept;
setupTab("Departments", intentDept, iconDept);
// PostBoard Activity
Intent intentBoard = new Intent().setClass(this, BoardActivity.class);
int iconBoard = R.drawable.ic_tab_board;
setupTab("Postboard", intentBoard, iconBoard);
// Social Network connection
// Check first to see if there are Social Network links if not don't
// show tab.
if (Startup.msMain.locations[Startup.nChosenLocation].social_media_feeds.length == 0) {
} else {
Intent intentSocial = new Intent().setClass(this,
SocialActivity.class);
int iconSocial = R.drawable.ic_tab_social;
setupTab("Social Media", intentSocial, iconSocial);
}
// Links Activity
Intent intentLinks = new Intent().setClass(this, LinksActivity.class);
int iconLinks = R.drawable.ic_tab_link;
setupTab("Links", intentLinks, iconLinks);
// set startup tab
tabHost.setCurrentTab(0);
}
private void setupTab(final String tag, Intent intent, int img) {
View tabview = createTabView(mTabHost.getContext(), tag, img);
TabSpec setContent = mTabHost.newTabSpec(tag).setIndicator(tabview)
.setContent(intent);
mTabHost.addTab(setContent);
}
private static View createTabView(final Context context, final String text,
int img) {
View view = LayoutInflater.from(context)
.inflate(R.layout.tabs_bg, null);
TextView tv = (TextView) view.findViewById(R.id.tabsText);
tv.setText(text);
ImageView icon = (ImageView) view.findViewById(R.id.tabsIcon);
icon.setBackgroundDrawable(context.getResources().getDrawable(img));
return view;
}
}
为了彻底起见,这里是我出现错误时的日志。

是否有一种方法可以强制我的小部件活动在onResume()或onPause()上重新绘制,迫使它完全杀死活动,从而迫使它再次使用onCreate方法?或者还有其他解决这个问题的方法吗?谢谢你的建议!
问题是
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
正在剪切活动视图的底部。我不知道这是一个错误还是什么,但修复是添加以下行。
getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
