利用 Bundle 实现 Android Activity 间消息的传递

核心提示：}}package com.ray.test;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.MotionEvent;public class TestBundl

}

}

package com.ray.test;

import android.app.Activity;

import android.content.Intent;

import android.os.Bundle;

import android.view.MotionEvent;

public class TestBundle extends Activity {

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

}

public boolean onTouchEvent(MotionEvent event) {

Intent intent = new Intent();

intent.setClass(TestBundle.this, Target.class);

Bundle mBundle = new Bundle();

mBundle.putString("Data", "ray'blog");//压入数据

intent.putExtras(mBundle);

startActivity(intent);

finish();

return super.onTouchEvent(event);

}

}

将要跳转到的活动代码：

Java代码

package com.ray.test;

import android.app.Activity;

import android.os.Bundle;

public class Target extends Activity{

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

Bundle bundle = getIntent().getExtras();

String data=bundle.getString("Data");//读出数据

setTitle(data);

}

}

package com.ray.test;

import android.app.Activity;

import android.os.Bundle;

public class Target extends Activity{

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

Bundle bundle = getIntent().getExtras();

String data=bundle.getString("Data");//读出数据

setTitle(data);

}

}
