二、详解

默认显示状态

 

1.FEATURE_CUSTOM_TITLE详解

this.requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);  setContentView(R.layout.main);

 

这是因为没有设置Featrue

在上面代码后加:getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.title);

 

自定义标题完成,它是一个xml文件布局

<?xml version="1.0" encoding="utf-8"?>  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"      android:layout_width="wrap_content"      android:layout_height="wrap_content" >        <ImageView          android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:src="@drawable/ic_launcher"          />        <TextView          android:id="@+id/text"          android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:layout_alignParentLeft="true"          android:textColor="#000000"          android:text="FEATURE_CUSTOM_TITLE" />    </LinearLayout>  

2.FEATURE_INDETERMINATE_PROGRESS详解

this.requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);  setContentView(R.layout.main);  getWindow().setFeatureInt(Window.FEATURE_INDETERMINATE_PROGRESS, R.layout.progress);  setProgressBarIndeterminateVisibility(true);  

<?xml version="1.0" encoding="utf-8"?>  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"      android:layout_width="wrap_content"      android:layout_height="wrap_content" >        <ProgressBar          android:id="@+id/progress"          style="?android:attr/progressBarStyleSmallTitle"          android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:layout_gravity="center_vertical" >      </ProgressBar>    </LinearLayout>
