android开发 - 拍照和选择本地图片库

1.首先在布局文件中定义两个按钮

 2.开启摄像头或者选择本地库

private final int IMAGE_RESULT_CODE = 1;//拍照意图回传值结果码</span>

private final int IMAGE_RESULT_OPEN_CODE = 2;//选择本地库
    private ImageView imageView;

protected void onCreate(Bundle savedInstanceState) {

<span > </span>Button btn1 = (Button)this.findViewById(R.id.button1);

<span > </span>Button btn2 = (Button)this.findViewById(R.id.button2);

<span > </span>btn1.setOnClickListener(new View.OnClickListener(){

<span > </span>@Override</span>

<span > </span>public void onClick(View v){   <span style="font-family: Arial, Helvetica, sans-serif;">   </span>

<span style="font-family: Arial, Helvetica, sans-serif;"><span >      </span>//拍照意图</span>

Intent intent = new Intent(android.provider.MediaStore.ACTION_VIDEO_CAPTURE);
      startActivityForResult(intent, IMAGE_RESULT_CODE);

<span > </span>}

<span > </span>});

btn2.setOnClickListener(new View.OnClickListener(){

<span >   </span>@Override

<span >   </span>public void onClick(View v){

<span >     </span>//选择图片库的图片
      Intent intent2 = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
      startActivityForResult(intent2, IMAGE_RESULT_OPEN_CODE);

<span >     </span>}

<span >     </span>});

<span >     </span>imageView = (ImageView)this.findViewById(R.id.icon_people_imgview);

<span >   </span> }

<span > </span>
<span > </span>

<span >   </span>//activity返回操作
<span >   </span>@Override
<span >   </span>protected void onActivityResult(int requestCode, int resultCode, Intent data) {
<span >     </span>//表示拍照返回后的显示结果
<span >     </span>if(requestCode == 1 && resultCode == RESULT_OK){
<span >       </span>Bundle bundle = data.getExtras();
<span >       </span>Bitmap bitmap = (Bitmap)bundle.get("data");
<span >       </span>imageView.setImageBitmap(bitmap);
<span >     </span>//表示选择本地图片库后的图片显示结果
<span >     </span>} else if(requestCode == 2 && resultCode == RESULT_OK) {
<span >       </span>imageView.setImageURI(data.getData());
<span >     </span>}
<span >     </span>super.onActivityResult(requestCode, resultCode, data);
<span >   </span>}

OK了，然后不管是拍摄的照片，还是本地库选择的图片，就会被陈列在ImageView控件上

那么接下来的工作就该是图片上上传了
