android 页面转换

通过setContentView来改变布局

很简单

ViewchangeActivity.java

package idrc.change;

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

public class ViewchangeActivity extends Activity {
/** Called when the activity is first created. */
    @Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Button m_Button01=(Button)findViewById(R.id.button01);
        m_Button01.setOnClickListener(new Button.OnClickListener()
        {

            @Override
public void onClick(View v) {
// TODO Auto-generated method stub
                jumpTolayout2();
            }

        }
        );
    }
//跳转到第二个布局
    public void jumpTolayout2()
    {
           setContentView(R.layout.mylayout);
           Button m_Button02=(Button)findViewById(R.id.button02);
           m_Button02.setOnClickListener(new Button.OnClickListener()
           {

               @Override
public void onClick(View v) {
// TODO Auto-generated method stub
                   jumpTolayout1();
               }

           }
           );
    }
//跳转到第一个布局
    public void jumpTolayout1()
    {
           setContentView(R.layout.main);
           Button m_Button01=(Button)findViewById(R.id.button01);
           m_Button01.setOnClickListener(new Button.OnClickListener()
           {

               @Override
public void onClick(View v) {
// TODO Auto-generated method stub
                   jumpTolayout2();
               }

           }
           );
    }
}
