本文介绍了如何在Android中通过Intent实现两个Activity之间的页面跳转，并详细阐述了如何在跳转过程中传递数据，包括创建Intent对象、设置键值对、获取目标Activity传来的数据等关键步骤。

第一个Activity

public class activity02 extends Activity {
    /** Called when the activity is first created. */
	private Button myButton = null; //申明为成员变量
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        Button myButton = (Button)findViewById(R.id.myButton);//获得Button
        myButton.setOnClickListener(new MyButtonListener());//将监听器捆绑在myButton上
        TextView myTextView = (TextView)findViewById(R.id.myTextView);
        myTextView.setText("jdfjei");
        myButton.setText("wfisdjf" + "\n" + "test");
        
    }
     class MyButtonListener implements OnClickListener{
                 //设置监听器，然后复写Oclick方法   
	
		@Override
		public void onClick(View v) {
			// TODO Auto-generated method stub
			Intent intent =new  Intent(); //生成Intent对象
			intent.putExtra("testIntent", "123");//加入一组键值对，传递数据

			intent.setClass(activity02.this,OtherActivity.class);//实现跳转功能
			activity02.this.startActivity(intent);
		
		}	
    }
}

另一个Activity

public class OtherActivity extends Activity{
	private TextView myTextView = null;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		setContentView(R.layout.other);
		Intent intent = getIntent();
		String value = intent.getStringExtra("testIntent");//取得testIntent的值
		myTextView = (TextView)findViewById(R.id.myTextView);
		myTextView.setText(value);
		
	}

}
