Android 拍照加裁剪处理方式

1.调用系统的照相机程序

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

startActivityForResult(intent, TAKE_PHOTO_WITH_DATA);

2.在onActivityResult中处理返回的data

final Bitmap photo = data.getParcelableExtra("data");

如果不需要做剪切处理就可以直接使用图片了，比如显示到ImageView上

imageView.setImageBitmap(photo);

如果需要做剪切处理，就继续向下执行

3.做剪切处理

Intent intent = new Intent("com.android.camera.action.CROP");

intent.setType("image/*");

intent.putExtra("data", data);

intent.putExtra("crop", "true");

intent.putExtra("aspectX", 1);

intent.putExtra("aspectY", 1);

intent.putExtra("outputX", 128);

intent.putExtra("outputY", 128);

intent.putExtra("return-data", true);

startActivityForResult(intent, PHOTO_PICKED_WITH_DATA);

4.在onActivityResult中处理

与第二步相同。

完整代码：

public class SdCardUriTestActivity extends Activity {

/** Called when the activity is first created. */

private Button btnTake = null;

private ImageView lblImage = null;



private static final int PHOTO_PICKED_WITH_DATA = 3021;

private static final int CAMERA_WITH_DATA = 3023;



@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);



btnTake = (Button)findViewById(R.id.btnTake);

lblImage = (ImageView)findViewById(R.id.lblImage);

btnTake.setOnClickListener(new View.OnClickListener() {



@Override

public void onClick(View v) {

// TODO Auto-generated method stub

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

startActivityForResult(intent, CAMERA_WITH_DATA);

}

});



}



@Override

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

// TODO Auto-generated method stub

if(resultCode!=RESULT_OK)

return;

switch(requestCode){

case CAMERA_WITH_DATA:

final Bitmap photo = data.getParcelableExtra("data");

if(photo!=null){

doCropPhoto(photo);

}

case PHOTO_PICKED_WITH_DATA:

Bitmap photo1 = data.getParcelableExtra("data");

if(photo1!=null){

lblImage.setImageBitmap(photo1);

}



}

}



protected void doCropPhoto(Bitmap data){

Intent intent = getCropImageIntent(data);

startActivityForResult(intent, PHOTO_PICKED_WITH_DATA);

}



public static Intent getCropImageIntent(Bitmap data) {

Intent intent = new Intent("com.android.camera.action.CROP");

intent.setType("image/*");

intent.putExtra("data", data);

intent.putExtra("crop", "true");

intent.putExtra("aspectX", 1);

intent.putExtra("aspectY", 1);

intent.putExtra("outputX", 128);

intent.putExtra("outputY", 128);

intent.putExtra("return-data", true);
