我修改了StopWatch演示Glass应用程序,以便在点击侧面时通过请求启动Camera活动。意图代码是从Google的文档中复制的。
当我点按时,我的应用程序的onPause回调被触发,但屏幕转换为黑色而不是相机预览。再次点击什么也没做 - onResume没有被调用。向下滑动确实会将我转换回StopWatch活动。
这看起来像是玻璃上的相机意图的错误,还是我的结果?
秒表活动
private static final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 100; // 1337 also doesn't work
public boolean onKeyDown(int keyCode, KeyEvent event) {
switch (keyCode) {
case KeyEvent.KEYCODE_DPAD_CENTER:
case KeyEvent.KEYCODE_ENTER:
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); // file:///mnt/sdcard/Pictures/MyCameraApp/IMG_20130812_105617.jpg
// start the image capture Intent
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
return true;
default:
return super.onKeyDown(keyCode, event);
}
}
