经过努力,我找到了解决办法。啊啊啊!!!
相机.xml:

你的相机活动应该是这样的:我只发布我认为你应该关注的主要部分,其余部分你可以实现。如果你卡在某个地方,请问我。首先,您应该从您的活动中调用:
final Button clickButton = (Button) findViewById(R.id.clickButton);
clickButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(final View view) {
camera.takePicture(null, null, mPicture);
}
});
你的 onPictureTaken() 应该是这样的:
/**
* 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();
}
}
}
};
这将显示捕获的图像,就像您上面提到的那样。
谢谢 :)
