我有一个模板列表，每个模板都在框架布局中， 每个模板都有主图像和 6 个代表颜色的矩形(见图像)
当我单击列表中的矩形时，焦点和边框颜色发生变化。即使我点击其他模板，它也会保持选中状态 我只想一次选择一个，这是模板类的代码。

最佳答案
我认为您应该从代码中的其他模板中取消选择所有其他边框 View 。为此:
1- 在 TemplateView 类中添加此方法:
private void deselectOtherBorderViews(TemplateView currentSelectedTemplate, LinearLayout layoutTemplateContainer) {
if (layoutTemplateContainer != null) {
int childCount = layoutTemplateContainer.getChildCount();
if (childCount > 0) {
int currentSelectedTemplateTag = (Integer) currentSelectedTemplate.getTag();
for (int i = 0; i < childCount; i++) {
View currentChild = layoutTemplateContainer.getChildAt(i);
if (currentChild != null) {
// cast the current view to a web template
TemplateView currentTemplate = (TemplateView) currentChild;
int currentTemplateTag = (Integer) currentTemplate.getTag();
if (currentTemplateTag != currentSelectedTemplateTag) {
// deselect the border view of the currentTemplate
ArrayList<BorderView> currentTemplateColorsIVs = currentTemplate.getColorsIVs();
if (currentTemplateColorsIVs != null && !currentTemplateColorsIVs.isEmpty()) {
for (BorderView btn : currentTemplateColorsIVs) {
btn.removeSelectionBorder();
}
}
}
}
}
}
}
}
2- 在 onClick() 方法中调用它(当用户在特定模板 View 中单击颜色时:
borderV.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// Deselect other border views from other web template views
deselectOtherBorderViews(TemplateView.this, SelecttemplateActivity.listemplates);
// The rest of your code...
注意:在 onPostExecute() 中加载它们时，不要忘记为模板 View 设置整数标签:
protected void onPostExecute(ArrayList<WebTemplate> webTemplates) {
int counter = 0;
for (WebTemplate wt : webTemplates) {
TemplateView tv = new TemplateView(getApplicationContext(), wt);
tv.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
tv.setTag(counter);
counter++;
listemplates.addView(tv);
}
希望对您有所帮助。
