Android笔记——不同apk之间传递参数与数据

http://dongyang555-126-com.iteye.com/blog/1308586

android编程的时候，有时候需要在不同的apk之间传递参数或数据，下面是一个简单的例子：

APK（1）的程序代码：

IntentSend.java:

package com.is; 

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

public class IntentSend extends Activity { 
Channel channel = new Channel(); 
Button szws; 

    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
        super.onCreate(savedInstanceState); 
        setContentView(R.layout.main); 
        szws = (Button)findViewById(R.id.szws); 
        szws.setOnClickListener(new Button.OnClickListener(){ 
public void onClick(View v) { 
Intent intent = new Intent(); 
Bundle bundle = new Bundle(); 
bundle.putString("channel", channel.channels[0]); 
intent.setClassName("com.bget", "com.bget.BinderGET"); 
intent.putExtras(bundle); 
startActivity(intent); 
} 
        }); 
    } 
} 

Channel.java:
 package com.is;
public class Channel {
 String channels[] = {
  "深圳卫视",
  "深圳电视剧",
  "深圳都市"
 };
}

APK（2）的程序代码：

IntentGet.java:
package com.ig;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class IntentGet extends Activity {
 TextView info;
 
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);  
        info =(TextView)findViewById(R.id.info);
       Bundle bundle = new Bundle();
     bundle = this.getIntent().getExtras();
        
        info.setText("现在播放的是：" + bundle.getString("channel"));
    }
}

程序中，主要是调用了Intent和Bundle的方法，Intent程序之间的跳转，Bundle程序之间数据的传递。

好用
