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
<"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" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerVertical="true" android:layout_toRightOf="@+id/titleTvLeft" android:paddingLeft="3dip"></ProgressBar> </RelativeLayout>
希望本文所述对大家Android程序设计有所帮助。
