Android中ImageView实现选择本地图片并显示功能

运行结果：

模拟器图库就三张 没办法~画质挺感人~

一个隐式意图

布局文件：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ImageView
 android:id="@+id/image_choose"
 android:layout_width="250dp"
 android:layout_height="250dp"
 android:background="#CC0000"
 android:layout_centerHorizontal="true"
 android:layout_marginTop="30dp"
 android:src="@drawable/default_bg"
 android:padding="5dp"
 />
</RelativeLayout>

MainActivity.class

package com.example.chooseimage;
import android.os.Bundle;
import android.provider.MediaStore;
import android.app.Activity;
import android.content.Intent;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.Window;
import android.widget.ImageView;
public class MainActivity extends Activity implements OnClickListener {
private ImageView image_choose;
@Override
protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 requestWindowFeature(Window.FEATURE_NO_TITLE);
 setContentView(R.layout.activity_main);
 image_choose = (ImageView) findViewById(R.id.image_choose);
 image_choose.setOnClickListener(this);
}
@Override
public void onClick(View v) {
 // TODO Auto-generated method stub
 switch (v.getId()) {
 case R.id.image_choose: {
  Intent intent = new Intent(Intent.ACTION_PICK, null);
  intent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
    "image/*");
  startActivityForResult(intent, 0x1);
  break;
 }
 }
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
 // TODO Auto-generated method stub
 if (requestCode == 0x1 && resultCode == RESULT_OK) {
  if (data != null) {
   image_choose.setImageURI(data.getData());
  }
 }
 super.onActivityResult(requestCode, resultCode, data);
}
}
