自定义标题栏

1.自定义标题栏layout文件：custom_title.xml

TextView放在左边

01 <?xml version="1.0" encoding="utf-8"?>
02 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/screen"
03     android:layout_width="match_parent" android:layout_height="match_parent"
04     android:orientation="vertical">
05     <TextView android:id="@+id/title_text"
06         android:layout_width="wrap_content"
07         android:layout_height="wrap_content"
08         android:layout_alignParentLeft="true"
09         android:textAppearance="?android:attr/textAppearanceMedium"
10         android:text="@string/info_name" />
11 </RelativeLayout>

2.在onCreate函数中，设置FEATURE_CUSTOM属性，并取得felt_text，以便对标题栏进行动态修改

1 requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
2 setContentView(R.layout.main);
3 getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.custom_title);
4 final TextView leftText = (TextView) findViewById(R.id.left_text);
