android复制按钮,android-如何在片段中添加另一个按钮

真正的答案之前只有一些提示：

>使用第一个大写字母作为班级名称

>请勿将首字母大写用作ID

>不要如下创建新的OnClickListener实例,而要实现接口

>全局意图变量没有多大意义

现在是“快速”答案：

public class Courses extends Fragment {

Intent intent, anotherIntent;

@Nullable

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container,

Bundle savedInstanceState) {

View root = inflater.inflate(R.layout.courses, container, false);

intent = new Intent(getActivity(), Software_course.class);

anotherIntent = new Intent(getActivity(), YourSecondActivityName.class);

final Button button = (Button) root.findViewById(R.id.software_Course);

final Button button2 = (Button) root.findViewById(R.id.software_Course2);

button.setOnClickListener(new View.OnClickListener() {

public void onClick(View v) {

startActivity(intent);

}

});

button2.setOnClickListener(new View.OnClickListener() {

public void onClick(View v) {

startActivity(anotherIntent);

}

});

return root;

}

}

这是我的建议：

public class Courses extends Fragment implements View.OnClickListener {

@Nullable

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container,

Bundle savedInstanceState) {

View root = inflater.inflate(R.layout.courses, container, false);

root.findViewById(R.id.software_Course).setOnClickListener(this);

root.findViewById(R.id.software_Course2).setOnClickListener(this);

return root;

}

public void onClick(View v) {

switch(v.getId()) {

case R.id.software_Course:

startActivity(new Intent(getActivity(), Software_course.class));

break;

case R.id.software_Course2:

startActivity(new Intent(getActivity(), YourSecondActivityName.class));

break;

}

}

}
