java如何从自定义视图访问片段中的onclicklistener
我有一组单选按钮,排列成3x3的网格。当我点击任何单选按钮时,都会出现一个祝酒词,但是在自定义视图中调用了onclick方法,我希望在片段中调用onclick方法
我的自定义视图
public class ToggleButtonGroupTableLayout extends TableLayout implements OnClickListener {
OnItemClickCallback onItemClickCallback;
private static final String TAG = "ToggleButtonGroupTableLayout";
private RadioButton activeRadioButton;
/**
* @param context
*/
public ToggleButtonGroupTableLayout(Context context) {
super(context);
// TODO Auto-generated constructor stub
}
public ToggleButtonGroupTableLayout(Context context,OnItemClickCallback onItemClickCallback) {
super(context);
this.onItemClickCallback = onItemClickCallback;
// TODO Auto-generated constructor stub
}
/**
* @param context
* @param attrs
*/
public ToggleButtonGroupTableLayout(Context context, AttributeSet attrs) {
super(context, attrs);
// TODO Auto-generated constructor stub
}
@Override
public void onClick(View v) {
final RadioButton rb = (RadioButton) v;
if ( activeRadioButton != null ) {
activeRadioButton.setChecked(false);
}
rb.setChecked(true);
Toast.makeText(getContext(),rb.getText().toString(), Toast.LENGTH_SHORT).show();
activeRadioButton = rb;
}
public void radio_button_data(String s) {
}
/* (non-Javadoc)
* @see 安卓.widget.TableLayout#addView(安卓.view.View, int, 安卓.view.ViewGroup.LayoutParams)
*/
@Override
public void addView(View child, int index,
安卓.view.ViewGroup.LayoutParams params) {
super.addView(child, index, params);
setChildrenOnClickListener((TableRow)child);
}
/* (non-Javadoc)
* @see 安卓.widget.TableLayout#addView(安卓.view.View, 安卓.view.ViewGroup.LayoutParams)
*/
@Override
public void addView(View child, 安卓.view.ViewGroup.LayoutParams params) {
super.addView(child, params);
setChildrenOnClickListener((TableRow)child);
}
private void setChildrenOnClickListener(TableRow tr) {
final int c = tr.getChildCount();
for (int i=0; i < c; i++) {
final View v = tr.getChildAt(i);
if ( v instanceof RadioButton ) {
v.setOnClickListener(this);
}
}
}
public int getCheckedRadioButtonId() {
if ( activeRadioButton != null ) {
return activeRadioButton.getId();
}
return -1;
}
我的碎片
public class Post_Property_1 extends Fragment{
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
ToggleButtonGroupTableLayout.OnItemClickCallback callback = null;
// Inflate the layout for this fragment
final View v = inflater.inflate(R.layout.post_property_1, container, false);}
请帮助我如何在片段活动中从自定义视图访问onclick。提前谢谢
