Android:标签顶部的版式 [英] Android: Layout on top of tabs

问题描述

如您所见，线性布局位于选项卡的顶部.我想要的是将LinearLayout底部与标签顶部对齐.

As you can see, a linearlayout is on top of the tabs. What I want is to align the LinearLayout bottom to the tabs top.

或者将RelativeLayout对准选项卡顶部也可以.

Alternatively aligning the RelativeLayout to the top of tabs may also work.

以下是上面视图的相应代码:

Here's the corresponding code for the view above:

<?xml version="1.0" encoding="UTF-8"?>
<RelativeLayout android:id="@+id/RelativeLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android">
    <LinearLayout android:layout_width="fill_parent" android:orientation="vertical" android:layout_height="wrap_content" android:id="@+id/LinearLayout02" android:layout_alignParentBottom="true">
        <FrameLayout android:id="@+id/FrameLayout02" android:layout_height="wrap_content" android:layout_width="fill_parent" android:paddingTop="20sp" android:paddingBottom="20sp">
            <ImageButton android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/record" android:layout_gravity="center_horizontal" android:id="@+id/RecordImageButton"></ImageButton>
        </FrameLayout>
        <SeekBar android:id="@+id/SeekBar01" android:layout_height="wrap_content" android:layout_width="fill_parent" android:paddingBottom="5sp" android:paddingLeft="10sp" android:paddingRight="10sp"></SeekBar>
        <FrameLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="@+id/FrameLayout03">
            <LinearLayout android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/LinearLayout02" android:layout_gravity="center_horizontal">
                <ImageButton android:layout_width="wrap_content" android:id="@+id/ImageButton01" android:layout_height="wrap_content" android:src="@drawable/play_rev"></ImageButton>
                <ImageButton android:layout_width="wrap_content" android:id="@+id/ImageButton02" android:layout_height="wrap_content" android:src="@drawable/play_stop"></ImageButton>
                <ImageButton android:layout_width="wrap_content" android:id="@+id/ImageButton03" android:layout_height="wrap_content" android:src="@drawable/play"></ImageButton>
            </LinearLayout>
        </FrameLayout>
    </LinearLayout>
</RelativeLayout>

以下是标签的代码:

<?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">

    <RelativeLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">

        <TabWidget
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@android:id/tabs"
        android:layout_alignParentBottom="true" />

        <FrameLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:id="@android:id/tabcontent" />

    </RelativeLayout>
</TabHost>

MainActivity，它为每个选项卡设置一个活动:

MainActivity, which sets an activity for each tab:

public void initTabs()
{
    Resources res = getResources(); // Resource object to get Drawables
    TabHost tabHost = getTabHost();  // The activity TabHost
    TabHost.TabSpec spec;  // Resusable TabSpec for each tab
    Intent intent;  // Reusable Intent for each tab

    intent = new Intent().setClass(this, FirstActivity.class);
    spec = tabHost.newTabSpec("tab1").setIndicator("Tab",
                      res.getDrawable(R.drawable.ic_tab_artists))
                  .setContent(intent);
    tabHost.addTab(spec);

    intent = new Intent().setClass(this, SecondActivity.class);
    spec = tabHost.newTabSpec("tab2").setIndicator("Tab 2",
                      res.getDrawable(R.drawable.ic_tab_artists))
                  .setContent(intent);
    tabHost.addTab(spec);

    intent = new Intent().setClass(this, ThridActivity.class);
    spec = tabHost.newTabSpec("tab3").setIndicator("Tab 3",
                      res.getDrawable(R.drawable.ic_tab_artists))
                  .setContent(intent);
    tabHost.addTab(spec);

    tabHost.setCurrentTab(0);
}

推荐答案

您可以创建参数和规则:

You can create params and rules :

RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT)

params.addRule(RelativeLayout.Top, anotherView.getId());

此行意味着一个视图的底部将位于另一个视图的顶部...这可以工作，但建议在xml中进行.

This line means that one view bottom will be top of another... This can works but it is adviced to do that in xml.
