android本地图片,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：

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent" >

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"

/>

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

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);

}

}
