Android笔记(1)——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。
