Java Android定制相机预览?
我正在为Java Android定制相机预览?,java,android,camera,android-camera,Java,Android,Camera,Android Camera,我正在为android创建一个camera应用程序。 我想要我的相机预览活动,如下图(例如)。我想将我的相机预览活动分为四个或多个部分 也就是说,在我从相机中单击一张图片后,当我返回到我的(相机图像预览活动)活动时,我希望将活动屏幕分为四个或更多部分,每个部分都应该有该预览图像 原因是我想用imagerender script效果来试验每个预览[但这个解决方案超出了我的问题范围,因为我知道如何使用render scripts],而且每个部分都应该有单独的渲染 有谁能帮我找到解决办法吗 这将是一

我想要我的相机预览
活动,如下图(例如)。我想将我的相机预览
活动分为四个或多个部分
也就是说,在我从相机
中单击一张图片后,当我返回到我的(相机图像预览活动)活动
时,我希望将活动屏幕
分为四个或更多部分,每个部分都应该有该预览图像
原因是我想用imagerender script
效果来试验每个预览[但这个解决方案超出了我的问题范围,因为我知道如何使用render scripts],而且每个部分都应该有单独的渲染
有谁能帮我找到解决办法吗
这将是一个很大的帮助,如果有任何例子或教程为这一点
提前谢谢。经过努力,我找到了解决办法。是啊 camera.xml:

您的onPictureTaken()应该如下所示:
/**
* This will be called after taking picture from camera.
*/
final transient private PictureCallback mPicture = new PictureCallback() {
/**
* After taking picture, onPictureTaken() will be called where image
* will be saved.
*
*/
@Override
public void onPictureTaken(final byte[] data, final Camera camera) {
OutputStream outStream = null;
try {
outStream = new BufferedOutputStream(new FileOutputStream(
mGetFile));
outStream.write(data); // Write the data to corresponding place.
((FrameLayout) findViewById(R.id.preview))
.setVisibility(View.GONE);
((LinearLayout) findViewById(R.id.imageViewLayout))
.setVisibility(View.VISIBLE);
final Options options = new Options();
options.inScaled = true;
options.inPurgeable = true;
// to scale the image to 1/8
options.inSampleSize = 8;
Bitmap imageBitmap = BitmapFactory.decodeByteArray(data, 0,
data.length, options);
ImageView image1 = (ImageView) findViewById(R.id.img1);
ImageView image2 = (ImageView) findViewById(R.id.img2);
ImageView image3 = (ImageView) findViewById(R.id.img3);
ImageView image4 = (ImageView) findViewById(R.id.img4);
image1.setImageBitmap(imageBitmap);
image2.setImageBitmap(imageBitmap);
image3.setImageBitmap(imageBitmap);
image4.setImageBitmap(imageBitmap);
} catch (FileNotFoundException e) {
camera.release();
} catch (IOException e) {
camera.release();
} finally {
try {
outStream.close();
} catch (IOException e) {
camera.release();
}
}
}
};
这将显示您上面提到的捕获图像

谢谢:)单击这四个部分后,您希望看到什么?我希望预览在相机表面分为四个部分,并在使用此效果拍摄照片时保存。您希望单击这四个部分时看到什么?我希望预览在相机表面分为四个部分,并在使用此效果拍摄照片时保存。此处,如果您希望预览的图像超过4个,那么最好使用GridLayout,因为管理线性布局有点复杂。在这里,如果您希望预览的图像超过4个,那么最好使用GridLayout,因为管理线性布局有点复杂。
