thank you 谢谢
public class MainActivity extends AppCompatActivity {
public static final int CAPTURE_IMAGE_FULLSIZE_ACTIVITY_REQUEST_CODE = 1777;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
File file = new File(Environment.getExternalStorageDirectory()+File.separator + "image.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file));
startActivityForResult(intent, CAPTURE_IMAGE_FULLSIZE_ACTIVITY_REQUEST_CODE);
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
//Check that request code matches ours:
if (requestCode == CAPTURE_IMAGE_FULLSIZE_ACTIVITY_REQUEST_CODE) {
//Get our saved file into a bitmap object:
File file = new File(Environment.getExternalStorageDirectory() + File.separator + "image.jpg");
Bitmap bitmap = decodeSampledBitmapFromFile(file.getAbsolutePath(), 1000, 700);
}
}
public static Bitmap decodeSampledBitmapFromFile(String path, int reqWidth, int reqHeight) {
//First decode with inJustDecodeBounds=true to check dimensions
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeFile(path, options);
// Calculate inSampleSize, Raw height and width of image
final int height = options.outHeight;
final int width = options.outWidth;
options.inPreferredConfig = Bitmap.Config.RGB_565;
int inSampleSize = 1;
if (height > reqHeight) {
inSampleSize = Math.round((float) height / (float) reqHeight);
}
int expectedWidth = width / inSampleSize;
if (expectedWidth > reqWidth) {
//if(Math.round((float)width / (float)reqWidth) > inSampleSize) // If bigger SampSize..
inSampleSize = Math.round((float) width / (float) reqWidth);
}
options.inSampleSize = inSampleSize;
// Decode bitmap with inSampleSize set
options.inJustDecodeBounds = false;
return BitmapFactory.decodeFile(path, options);
}
}
You can try this code to save your image to internal storage: 您可以尝试使用以下代码将图像保存到内部存储中:
FileOutputStream fos;
try {
fos = openFileOutput(FILENAME, Context.MODE_PRIVATE);
// You can also use .JPG
yourBitmap.compress(Bitmap.CompressFormat.PNG, 100, fos);
}
catch (FileNotFoundException e) {
Log.e(TAG, e.getMessage());
}
catch (IOException e) {
Log.e(TAG, e.getMessage());
} finally {
fos.close();
}

EDIT 编辑
For saving your full size image file to internal storage, you'll have to change your 要将完整尺寸的图像文件保存到内部存储中,您必须更改
File file = new File(Environment.getExternalStorageDirectory()+File.separator + "image.jpg");
to 至
File file = new File(context.getFilesDir(), "image.jpg");
getFilesDir() returns internal directory of your app. getFilesDir()返回应用程序的内部目录。 You will find more detailed information here: https://developer.android.com/training/basics/data-storage/files.html#WriteInternalStorage
