两个apk之间对应传输数据

test01 跳到test02的activity中,并且传输数据.
test02获取数据 ,同时也可以返回数据给test01.



test01的activity:

package cn.test01;

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

public class Test01Activity extends Activity {
	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		Button button = (Button) findViewById(R.id.button);
		button.setOnClickListener(new OnClickListener() {
			public void onClick(View v) {
				ComponentName componetName = new ComponentName(
				// 这个是另外一个应用程序的包名
						"cn.test02",
						// 这个参数是要启动的Activity
						"cn.test02.Test02Activity");
				Intent intent = new Intent();

				intent.putExtra("data", "我是Test01Activity类");
				intent.setComponent(componetName);
				startActivityForResult(intent, 1);// 发送数据,并且可以获取返回数据
			}
		});
	}

	/**
	 * 获取返回数据的方法
	 */
	protected void onActivityResult(int requestCode, int resultCode, Intent data) {
		super.onActivityResult(requestCode, resultCode, data);
		switch (requestCode) {
		case 1:
			if (resultCode == RESULT_OK) {
				System.out.println("获取返回的数据= " + "   "
						+ data.getStringExtra("data02"));
			}
			break;

		}
	}
}
test01的xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/hello"
    />
    
    <Button android:id="@+id/button"  android:layout_width="fill_parent" 
    android:layout_height="wrap_content" android:text="跳转到Test02项目的Test02Activity类" />
</LinearLayout>








test02的activity

package cn.test02;

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;

public class Test02Activity extends Activity {
	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);

		// 改变文字内容，标志这是从activity跳转过来的
		TextView texView = (TextView) findViewById(R.id.text1);
		Intent intent = getIntent();
		String value = intent.getStringExtra("data");// 获取对应传过来的数据
		if (value != null && !value.equals("")) {
			texView.setText(value);// 这里将显示“这是跳转过来的！来自Jar02Activity
		} else {
			System.out.println("空的参数");
		}

		// 当点击时返回数据给test01
		Button shuaka_button = (Button) findViewById(R.id.button);
		shuaka_button.setOnClickListener(new OnClickListener() {
			public void onClick(View v) {
				Uri data = Uri.parse("one................");
				Intent result = new Intent(null, data);
				result.putExtra("data02", "我是来自test02的是数据");
				setResult(RESULT_OK, result);
				finish();
			}
		});

	}
}


test02 的xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView  android:id="@+id/text1"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"  />
    
    <Button android:id="@+id/button" android:layout_width="fill_parent" 
    android:layout_height="wrap_content" android:text="返回数据给test01" />
