Android编程自定义title bar(标题栏)示例
本文实例讲述了Android编程自定义titlebar(标题栏)的方法。分享给大家供大家参考，具体如下：
packagecom.test;
importandroid.app.Activity;
importandroid.content.Context;
importandroid.graphics.Canvas;
importandroid.graphics.Color;
importandroid.graphics.drawable.Drawable;
importandroid.os.Bundle;
importandroid.view.View;
importandroid.view.Window;
importandroid.view.animation.Animation;
importandroid.view.animation.TranslateAnimation;
importandroid.widget.ProgressBar;
importandroid.widget.TextView;
publicclassTestextendsActivity{
/**Calledwhentheactivityisfirstcreated.*/
booleancustomTitleSupported;
publicvoidonCreate(BundlesavedInstanceState){
super.onCreate(savedInstanceState);
//checkifcustomtitleissupportedBEFOREsettingthecontentview!
customTitleSupported=requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
setContentView(R.layout.main);
//setcustomtitlebar
customTitleBar(getText(R.string.app_name).toString(),"helloworld!!");
}
publicvoidcustomTitleBar(Stringleft,Stringright){
if(right.length()>20)
right=right.substring(0,20);
//setupcustomtitle
if(customTitleSupported){
getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE,
R.layout.title);
TextViewtitleTvLeft=(TextView)findViewById(R.id.titleTvLeft);
TextViewtitleTvRight=(TextView)findViewById(R.id.titleTvRight);
titleTvLeft.setText(left);
titleTvRight.setText(right);
ProgressBartitleProgressBar;
titleProgressBar=(ProgressBar)findViewById(R.id.leadProgressBar);
//hidetheprogressbarifitisnotneeded
titleProgressBar.setVisibility(ProgressBar.GONE);
}
}
}
布局文件:title.xml
<?xmlversion="1.0"encoding="utf-8"?> <RelativeLayoutandroid:id="@+id/RelativeLayout01" android:layout_width="fill_parent"android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"> <TextViewandroid:layout_width="wrap_content" android:layout_height="wrap_content"android:id="@+id/titleTvLeft" android:text="left"></TextView> <TextViewandroid:layout_width="wrap_content" android:layout_height="wrap_content"android:id="@+id/titleTvRight" android:text="right"android:layout_alignParentRight="true"></TextView> <ProgressBarandroid: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>
