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"
- };
- }
-
复制代码 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"));
- }
- }
-
复制代码 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。 |
