Android笔记——不同apk之间传递参数与数据

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。
