它在galaxy S4上也能正常工作 拍摄图像时，相机会导致方向改变，此时您的活动会被破坏 这个类似的问题我在工作的时候也遇到了。 所以，为了停止定向，我使用了下面的代码 将这些添加到您的menifest文件中
public class Activity_MyDiary extends Write_MyArticle implements View.OnClickListener{
private final int DIARY_TYPE = 1;
private String title, comments;
public void init(){
setContentView(R.layout.activity_feed_mydiary);
activity = this;
mContext = this;
btn_plus = (Button)findViewById(R.id.btn_feed_myDiary_plus);
btn_plus.setOnClickListener(this);
btn_post = (Button)findViewById(R.id.btn_feed_myDiary_post);
btn_post.setOnClickListener(this);
btn_delete = (Button)findViewById(R.id.btn_feed_myDiary_delete);
btn_delete.setOnClickListener(this);
edit_title = (EditText)findViewById(R.id.edit_feed_myDiary_title);
edit_contents = (EditText)findViewById(R.id.edit_feed_myDiary_contents);
image = (ImageView)findViewById(R.id.image_feed_myDiary_captured);
