本文实例讲述了android编程自定义title bar(标题栏)的方法。分享给大家供大家参考，具体如下：

package com.test;
import android.app.activity;
import android.content.context;
import android.graphics.canvas;
import android.graphics.color;
import android.graphics.drawable.drawable;
import android.os.bundle;
import android.view.view;
import android.view.window;
import android.view.animation.animation;
import android.view.animation.translateanimation;
import android.widget.progressbar;
import android.widget.textview;
public class test extends activity {
  /** called when the activity is first created. */
 boolean customtitlesupported;
  public void oncreate(bundle savedinstancestate) {
    super.oncreate(savedinstancestate);
    //check if custom title is supported before setting the content view!
    customtitlesupported = requestwindowfeature(window.feature_custom_title);
    setcontentview(r.layout.main);
   //set custom titlebar
    customtitlebar(gettext(r.string.app_name).tostring(), "hello world!!");
  }
 public void customtitlebar(string left, string right) {
 if (right.length() > 20)
  right = right.substring(0, 20);
 // set up custom title
 if (customtitlesupported) {
  getwindow().setfeatureint(window.feature_custom_title,
   r.layout.title);
  textview titletvleft = (textview) findviewbyid(r.id.titletvleft);
  textview titletvright = (textview) findviewbyid(r.id.titletvright);
  titletvleft.settext(left);
  titletvright.settext(right);
  progressbar titleprogressbar;
  titleprogressbar = (progressbar) findviewbyid(r.id.leadprogressbar);
  // hide the progress bar if it is not needed
  titleprogressbar.setvisibility(progressbar.gone);
 }
 }
}

布局文件: title.xml

<?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">
 <textview android:layout_width="wrap_content"
 android:layout_height="wrap_content" android:id="@+id/titletvleft"

 <textview android:layout_width="wrap_content"
 android:layout_height="wrap_content" android:id="@+id/titletvright"
 android:text="right" android:layout_alignparentright="true"></textview>
 <progressbar android:id="@+id/leadprogressbar"
 style="?android:attr/progressbarstylesmall" android:layout_width="wrap_content"
 android:layout_height="wrap_content" android:layout_centervertical="true"
