我想制作一个我必须只打开前置摄像头的应用程序,我该如何使用意图？
private void captureImage() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);
intent.putExtra(MediaStore.EXTRA_OUTPUT,fileUri);
intent.putExtra("android.intent.extras.CAMERA_FACING",1);
// start the image capture Intent
startActivityForResult(intent,CAMERA_CAPTURE_IMAGE_REQUEST_CODE);
}
解决方法
java的
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
Uri photoUri = Uri.fromFile(getOutputPhotoFile());
intent.putExtra(MediaStore.EXTRA_OUTPUT,photoUri);
intent.putExtra("android.intent.extras.CAMERA_FACING",1);
startActivityForResult(intent,CAMERA_PHOTO_REQUEST_CODE);
其他/替代解决方案
private Camera openFrontFacingCameraGingerbread() {
int cameraCount = 0;
Camera cam = null;
Camera.CameraInfo cameraInfo = new Camera.CameraInfo();
cameraCount = Camera.getNumberOfCameras();
for (int camIdx = 0; camIdx < cameraCount; camIdx++) {
Camera.getCameraInfo(camIdx,cameraInfo);
if (cameraInfo.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
try {
cam = Camera.open(camIdx);
} catch (RuntimeException e) {
Log.e(TAG,"Camera Failed to open: " + e.toString());
}
}
}
return cam;
}
<uses-permission android:name="android.permission.CAMERA" /> <uses-feature android:name="android.hardware.camera" android:required="false" /> <uses-feature android:name="android.hardware.camera.front" android:required="false" />
only available in Gingerbread(2.3) and Up Android Version.
