我编码拍照并将其保存在外部存储中。它在我的平板电脑上运行良好，带有 sd 卡。但是，我的手机不支持 sd 卡时遇到了一些问题。谁能帮我编写代码以保存在内部存储中。谢谢！
((Button) findViewById(R.id.btnTaken))
.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
takeImage();
}
});
protected void takeImage() {
Log.i(TAG,"onClick event");
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd_HH-mm-ss");
String currentDateandTime = sdf.format(new Date());
String fileName = Environment.getExternalStorageDirectory().getAbsolutePath() +
"/Image_" + currentDateandTime + ".jpg";
mCamera.takePicture(fileName);
Toast.makeText(this, fileName + " saved", Toast.LENGTH_SHORT).show();
}
public void takePicture(final String fileName) {
Log.i(TAG, "Tacking picture");
PictureCallback callback = new PictureCallback() {
private String mPictureFileName = fileName;
@Override
public void onPictureTaken(byte[] data, Camera camera) {
Log.i(TAG, "Saving a bitmap to file");
Bitmap picture = BitmapFactory.decodeByteArray(data, 0, data.length);
try {
FileOutputStream out = new FileOutputStream(mPictureFileName);
picture.compress(Bitmap.CompressFormat.JPEG, 90, out);
picture.recycle();
mCamera.startPreview();
} catch (Exception e) {
e.printStackTrace();
}
}
};
Camera.ShutterCallback shutter = new Camera.ShutterCallback() {
public void onShutter() {
Log.e(getClass().getSimpleName(), "SHUTTER CALLBACK");
}
};
Camera.PictureCallback raw = new Camera.PictureCallback() {
public void onPictureTaken(byte[] data, Camera c) {
Log.e(getClass().getSimpleName(), "PICTURE CALLBACK RAW: " + data);
mCamera.startPreview();
}
};
mCamera.takePicture(shutter, raw, callback) ;
}
