<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="fill_horizontal"
android:background="#555333"
android:orientation="horizontal" >
<Button
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:layout_alignParentLeft="true"
    android:layout_centerVertical="true" />
   <TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"
    android:text="Title mswg" />

  </RelativeLayout>`

现在的问题是不是高度不change.My目标SDK是17。

The problem is not the height does not change.My target sdk is 17.

在此先感谢！

推荐答案

类似于你的code和真奇怪...我有运气这个样式（值）：

Looks similar to your code and it's strange... I have luck with this styles (values):

<style name="player" parent="@style/Theme.AppCompat">
    <item name="actionBarSize">90dp</item>
    <item name="actionBarStyle">@style/player.ActionBarStyle</item>
</style>

<style name="player.ActionBarStyle" parent="@style/Widget.AppCompat.ActionBar">
    <item name="android:background">@drawable/ab_bgr</item>
</style>

值-V11

values-v11

<style name="player" parent="@style/Theme.AppCompat">
    <item name="android:actionBarSize">90dp</item>
    <item name="android:actionBarStyle">@style/player.ActionBarStyle</item>
</style>

<style name="player.ActionBarStyle" parent="@style/Widget.AppCompat.ActionBar">
    <item name="android:background">@drawable/ab_bgr</item>
</style>

ActionBarActivity

ActionBarActivity

import android.support.v7.app.ActionBar;
import android.support.v7.app.ActionBarActivity;
....

View customView = activity.getLayoutInflater().inflate(R.layout.player_ab,null);

    ActionBar actionBar = getSupportActionBar();
    //float scale = activity.getResources().getDisplayMetrics().density;

    actionBar.setCustomView(customView, new ActionBar.LayoutParams(ActionBar.LayoutParams.MATCH_PARENT, ActionBar.LayoutParams.WRAP_CONTENT));//(int) (90*scale + 0.5f)));
    actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
