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：

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); 
 } 
}
