推荐答案
您可以保存在Android中的照片,无需随之而来的OutputStream和所有其他逻辑。下面是一个简单的食谱,这将做什么,我认为你所要完成。要特别注意的意图和如何使用它来设置图像的保存,因为这是我想你要去哪里错了。
You can save photos in Android without the need for an OutputStream and all the other logic that accompanies it. Here is a simple recipe which will do what I think you are trying to accomplish. Pay special attention to the Intent and how it is used to set up the saving of the image, as this is I think where you are going wrong.
public class PhotoActivity extends Activity implements OnClickListener {
private Button takePicture;
private String path;
private File imageFile;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.your_layout);
takePicture = (Button) findViewById(R.id.button1);
takePicture.setOnClickListener(this);
path = Environment.getExternalStorageDirectory() + "/my_image.png";
imageFile = new File(path);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.button1:
Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
Uri uri = Uri.fromFile(imageFile);
i.putExtra(MediaStore.EXTRA_OUTPUT, uri);
startActivity(i);
break;
}
}
}
