Android开发之页面跳转

1.如何创建多个页面

右击src->New->Other->Android Activity->Next->Blank Activity->输入页面名字即可

2.跳转传参方式一：

MainActivity:

 public void goSecond(View v){
    	 //intent设置要跳转的页面：
        Intent intent =new Intent(this,SecondActivity.class);
        //设置要携带的参数
        intent.putExtra("MyData","chenlichen hen shuai");
        //跳转：
        startActivity(intent);
    }

SecondActivity:接收参数

	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_second);

         //获取参数：
		Intent i = this.getIntent();
		data = i.getStringExtra("MyData");
		//System.out.println("收到数据："+data);
		Toast.makeText(this, data, 0).show();
		
	}

3.跳转传参方式二：

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    public void goSecond(View v){
    	//intent 设置要跳转的页面
    	Intent intent=new Intent(this,SecondActivity.class);

        //使用Bundle绑定多个参数：
    	Bundle bundle = new Bundle();
    	bundle.putString("MyData", "duyong");
    	bundle.putInt("ID", 100);
    	intent.putExtras(bundle);
    	
    	//跳转
    	startActivity(intent);
    }
    
}

3.自动跳转

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //实例化一个线程
        Thread t = new Thread(new Runnable() {
			
			@Override
			public void run() {
				// TODO Auto-generated method stub
				 try {
						Thread.sleep(3000);
						//intent 设置要跳转的页面
				    	Intent intent=new Intent(MainActivity.this,SecondActivity.class);
				    	//跳转
				    	startActivity(intent);
					} catch (InterruptedException e) {
						// TODO Auto-generated catch block
						e.printStackTrace();
					}
			}
		});
        //启动线程；
        t.start();  
    }  
}
