Question

我正在尝试为我的片段添加动态视图。

我正在使用此代码：

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

    Button myButton = new Button(Builtprofile.context);
    myButton.setText("Press me");
    myButton.setBackgroundColor(Color.YELLOW);

      RelativeLayout myLayout = new RelativeLayout(Builtprofile.context);
      myLayout.setBackgroundColor(Color.BLUE);

      RelativeLayout.LayoutParams buttonParams = 
                new RelativeLayout.LayoutParams(
                    RelativeLayout.LayoutParams.WRAP_CONTENT, 
                    RelativeLayout.LayoutParams.WRAP_CONTENT);

      buttonParams.addRule(RelativeLayout.CENTER_HORIZONTAL);
      buttonParams.addRule(RelativeLayout.CENTER_VERTICAL);

      myLayout.addView(myButton, buttonParams);

    View rootView = inflater.inflate(R.layout.q1, container, false);

// I want to add myLayout in place of R.layout.q1

    return rootView;

}

Answer 1

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

    Button myButton = new Button(Builtprofile.context);
    myButton.setText("Press me");
    myButton.setBackgroundColor(Color.YELLOW);

    RelativeLayout.LayoutParams buttonParams = new RelativeLayout.LayoutParams(
                RelativeLayout.LayoutParams.WRAP_CONTENT, 
                RelativeLayout.LayoutParams.WRAP_CONTENT);

    buttonParams.addRule(RelativeLayout.CENTER_HORIZONTAL);
    buttonParams.addRule(RelativeLayout.CENTER_VERTICAL);

    View rootView = inflater.inflate(R.layout.q1, container, false);

    RelativeLayout myLayout = (RelativeLayout)rootView.findViewById(R.id.mainLayout);
    myLayout.setBackgroundColor(Color.BLUE);

    myLayout.addView(myButton, buttonParams);

    return rootView;
}

有一个空的xml布局，只有一个名为＆＃34; mainLayout＆＃34;的RelativeLayout（或者你想要调用的东西）。这样你就可以附加任何动态生成的控件

Answer 2

LayoutInflater vi = (LayoutInflater) getActivity()
                  .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = vi.inflate(R.layout.xml, null);

container.addView(v);
