android 调用系统图片浏览器并返回图片路径

package com.zm;import android.app.Activity;import android.content.Intent;import android.database.Cursor;import android.net.Uri;import android.os.Bundle;import android.provider.MediaStore;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;public class PicActivity extends Activity {    /** Called when the activity is first created. */private Button myButton_02 = null;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);                myButton_02 = (Button)findViewById(R.id.button_02);        myButton_02.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubIntent intent = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);startActivityForResult(intent, 1);}});    }    protected void onActivityResult(int requestCode, int resultCode, Intent data){if (resultCode == Activity.RESULT_OK){Uri uri = data.getData();Cursor cursor = this.getContentResolver().query(uri, null, null, null, null);cursor.moveToFirst();for (int i = 0; i < cursor.getColumnCount(); i++){// 取得图片uri的列名和此列的详细信息System.out.println(i + "-" + cursor.getColumnName(i) + "-" + cursor.getString(i));}}}            }

主要代码如上，只需在main.xml中加个Button声明即可。。。
