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 {
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"
android:text="left"></TextView>
<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"
android:layout_toRightOf="@+id/titleTvLeft" android:paddingLeft="3dip"></ProgressBar>
</RelativeLayout>
