android tabwidget 需要帮助
大家好,这是我在 android 中的选项卡布局的代码,我希望它们位于 scrren 的底部,目前它在屏幕顶部显示我
main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:layout_alignParentBottom="true"
android:gravity="bottom">
<TabHost 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">
<HorizontalScrollView android:scrollbars="none"
android:layout_width="fill_parent" android:layout_height="wrap_content">
<TabWidget android:id="@android:id/tabs"
android:layout_alignParentBottom="true" android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</HorizontalScrollView>
<FrameLayout android:id="@android:id/tabcontent"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:padding="5dp" />
</LinearLayout>
</TabHost>
</LinearLayout>
tab.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:background="@drawable/tab_background_selector" android:gravity="center"
android:orientation="vertical" android:padding="5dp"
android:layout_alignParentBottom="true" >
<ImageView android:id="@+id/tab_icon" android:layout_width="30dp"
android:layout_height="30dp" android:scaleType="fitCenter" />
<TextView android:id="@+id/tab_text" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:singleLine="true"
android:textStyle="bold" android:gravity="center_horizontal"
android:textSize="10sp" android:padding="3dip" android:ellipsize="marquee"
android:textColor="@drawable/tab_text_selector"
android:layout_alignParentBottom="true" />
</LinearLayout>
这是我的活动课程 TestActivity.java
import android.app.TabActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.ImageView;
import android.widget.TabHost;
import android.widget.TextView;
import android.widget.TabHost.TabSpec;
public class TestActivity extends TabActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.maiin);
final TabHost tabHost = (TabHost) getTabHost();
tabHost.addTab(createTab(MobiintheMorningActivity.class,
"Welcome", "Welcome", R.drawable.icon));
tabHost.setCurrentTab(0);
tabHost.getTabWidget().getChildAt(0).getLayoutParams().width = 85;
}
private TabSpec createTab(final Class<?> intentClass, final String tag,
final String title, final int drawable)
{
final Intent intent = new Intent().setClass(this, intentClass);
final View tab = LayoutInflater.from(getTabHost().getContext()).
inflate(R.layout.tab, null);
((TextView)tab.findViewById(R.id.tab_text)).setText(title);
((ImageView)tab.findViewById(R.id.tab_icon)).setImageResource(drawable);
return getTabHost().newTabSpec(tag).setIndicator(tab).setContent(intent);
}
}
这里我使用了 android:layout_alignParentBottom="true"
但完全没有效果我该怎么办?我缺少什么?提前致谢:Pragna
