知识的价值不在于占有，而在于使用。这篇文章主要讲述关于android：getSlotFromBufferLocked的问题相关的知识，希望能为你提供帮助。
今天写了个调用摄像头之后将照片贴在屏幕上面的demo，出现了这个问题。代码如下

package android.com.java.choosepictest; import android.app.Activity; import android.content.Intent; import android.graphics.Bitmap; import android.graphics.BitmapFactory; import android.net.Uri; import android.os.Bundle; import android.os.Environment; import android.provider.MediaStore; import android.util.Log; import android.view.View; import android.widget.Button; import android.widget.ImageView; import java.io.File; import java.io.FileNotFoundException; import java.io.IOException; public class MainActivity extends Activity { public static final int TAKE_PHOTO = 1; public static final int CROP_PHOTO = 2; private Button takePhoto; private ImageView picture; private Uri imageUri; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); takePhoto = (Button)findViewById(R.id.take_photo); picture = (ImageView)findViewById(R.id.picture); takePhoto.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { File outputImage = new File(Environment.getExternalStorageDirectory(),"output_image.jpg"); try{ if (outputImage.exists()){ outputImage.delete(); } outputImage.createNewFile(); }catch (IOException e){ e.printStackTrace(); } imageUri = Uri.fromFile(outputImage); android.util.Log.e("YPC","uri = "+imageUri); try { Bitmap mBitmap = BitmapFactory.decodeStream((getContentResolver().openInputStream(imageUri))); Log.e("YPC","bitmap = "+mBitmap); Log.e("YPC","getContentResolver().openInputStream(imageUri) = "+getContentResolver().openInputStream(imageUri)); picture.setImageBitmap(mBitmap); }catch (FileNotFoundException e){ e.printStackTrace(); } Intent intent = new Intent ("android.media.action.IMAGE_CAPTURE"); intent.putExtra(MediaStore.EXTRA_OUTPUT,imageUri); startActivityForResult(intent,TAKE_PHOTO); } }); }@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { switch (requestCode){ case TAKE_PHOTO: if (requestCode == RESULT_OK) { Intent intent = new Intent ("com.android.camera.action.CROP"); intent.setDataAndType(imageUri,"image/*"); intent.putExtra("scale",true); intent.putExtra(MediaStore.EXTRA_OUTPUT,imageUri); try { Bitmap mBitmap = BitmapFactory.decodeStream((getContentResolver().openInputStream(imageUri))); Log.e("YPC","bitmap = "+mBitmap); Log.e("YPC","getContentResolver().openInputStream(imageUri) = "+getContentResolver().openInputStream(imageUri)); picture.setImageBitmap(mBitmap); }catch (FileNotFoundException e){ e.printStackTrace(); } startActivityForResult(intent,CROP_PHOTO); } break; case CROP_PHOTO: if (resultCode == RESULT_OK){ try{ Bitmap bitmap = BitmapFactory.decodeStream((getContentResolver().openInputStream(imageUri))); picture.setImageBitmap(bitmap); android.util.Log.e("YPC","bitmap = "+bitmap); }catch (FileNotFoundException e){ e.printStackTrace(); } } break; default:break; } } }
