我想在片段布局中制作一个锁定屏幕按钮 我搜索了一些帮助并发现了相同的内容,但使用了一个Activity。

代码在这里: http://karanbalkar.com/2014/01/tutorial-71-implement-lock-screen-in-android/

我不知道如何改变它以片段形式工作?

请帮忙

我的代码:

public class Tab1fragment extends Fragment {

/**
 * @param args
 */
@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onActivityCreated(savedInstanceState);

}

@Override
public View onCreateView(LayoutInflater inflater,
        @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    return inflater.inflate(R.layout.tab1_layout, container, false);
}
public static void main(String[] args) {
    // TODO Auto-generated method stub

}

您必须详细了解Fragmenthttp://developer.android.com/reference/android/app/Fragment.html

首先,您必须在片段中实现View.OnClickListener,然后在onCreateView内创建一个视图,如:

View rootView = inflater.inflate(R.layout. tab1_layout, container, false);

所以你的片段变成了:

public class Tab1fragment extends Fragment implements View.OnClickListener {

.
.

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {


    View rootView = inflater.inflate(R.layout.tab1_layout, container, false);
    mDevicePolicyManager = ...
    mComponentName = ...
    Button btnEnableAdmin = (Button) rootView.findViewById(R.id.btnEnable);
    .
    .

    btnEnableAdmin.setOnClickListener(this);
    .
    .
    return rootView;

}

public void onClick(View v) {
    switch (v.getId()) {
         ...
    }
}

}
