Android編程8:頁(yè)面切換測(cè)試

本文博客鏈接: http://blog.csdn.net/jdh99 ,作者:jdh,轉(zhuǎn)載請(qǐng)注明.

軟件平臺(tái):win7 + eclipse + sdk

設(shè)計(jì)思路:

兩個(gè)頁(yè)面:mian和ok,每個(gè)頁(yè)面上有一個(gè)按鍵,點(diǎn)擊則可以互相切換

源代碼:

main.xml源代碼:

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/hello"
    />
<Button android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="下一頁(yè)面 "></Button>
</LinearLayout>

  

ok.xml源代碼:

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent">
    <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="上一頁(yè)面 " android:id="@+id/button1"></Button>
</LinearLayout>

  

makechoice源代碼:

    package com.makechoice;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class makechoice extends Activity
{
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Button btn = (Button)findViewById(R.id.button1);
        btn.setOnClickListener(new Button.OnClickListener()
        {
        	@Override
        	public void onClick(View v)
        	{
        		jump2ok();
        	}
        });
    }
    
    //跳到ok頁(yè)面
    public void jump2ok()
    {
    	setContentView(R.layout.ok);
    	//當(dāng)有按鍵按下跳到main頁(yè)面
        Button btn = (Button)findViewById(R.id.button1);
        btn.setOnClickListener(new Button.OnClickListener()
        {
        	@Override
        	public void onClick(View v)
        	{
        		jump2main();
        	}
        });
    }
    
  //跳到main頁(yè)面
    public void jump2main()
    {
    	setContentView(R.layout.main);
    	//當(dāng)有按鍵按下跳到ok頁(yè)面
        Button btn = (Button)findViewById(R.id.button1);
        btn.setOnClickListener(new Button.OnClickListener()
        {
        	@Override
        	public void onClick(View v)
        	{
        		jump2ok();
        	}
        });
    }
}
  

運(yùn)行效果圖:

注意:

類R中存放的ID號(hào)為當(dāng)前頁(yè)面的ID號(hào),所以findViewById函數(shù)捕獲的控件也為當(dāng)前頁(yè)面的控件
