1.调用系统的照相机程序
Intent intent = newIntent(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，比如输出到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 = newIntent("com.android.camera.action.CROP");
intent.setType("image
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 = newIntent(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 = newIntent("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);
return intent;
}
}
