客製化android activity的title

本文主要實現了，在Android下實現自定義的Title

主Activity如下：

package com.xiaochun91103; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.view.Window; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.TextView; public class CustomerTitle extends Activity { /** Called when the activity is first created. */ private Button left; private Button right; private TextView left_text,right_text; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_CUSTOM_TITLE); setContentView(R.layout.main); getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.customertitle); //設定自定義Title left_text = (TextView)findViewById(R.id.left_text); right_text = (TextView)findViewById(R.id.right_text); left = (Button)findViewById(R.id.left); left.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub left_text.setText("Left Title"); } }); right = (Button)findViewById(R.id.right); right.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub right_text.setText("Right Title"); } }); } }

 

佈局如下main.xml：

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="wrap_content" android:layout_height="fill_parent" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="用戶客製化Title" /> <Button android:id="@+id/left" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Change Left Title" /> <Button android:id="@+id/right" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Change Right Title" /> </LinearLayout>

 

title佈局文件customertitle.xml如下：

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/screen" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> <TextView android:id="@+id/left_text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:text="aaa" /> <TextView android:id="@+id/right_text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:text="bbb" /> </RelativeLayout>

 

上個截圖，運行結果如下：
