“我想让 list_item 响应点击事件并显示 toast 消息.. 请帮忙.. 提前致谢!”
最佳答案
这可能是因为您试图在 ListView 的项目单击监听器内执行单击。
您可以通过为 ListView 创建自定义适配器来修复它。 Customer ListView Adapter
创建此自定义适配器后，您可以获取description和loveBtn的引用，并对其进行点击操作。
你的适配器的 getView() 代码将是这样的 -
@Override
public View getView(int position, View convertView, ViewGroup parent) {
if(convertView==null) {
LayoutInflater layoutInflater = LayoutInflater.from(context);
convertView=layoutInflater.inflate(R.layout.list_row, null);
TextView description=convertView.findViewById(R.id.eventDesc);
Button loveBtn=convertView.findViewById(R.id.loveButton);
}
description.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (!TextUtils.isEmpty(mEventUrl)) {
Intent openLinkInBrowser = new Intent(Intent.ACTION_VIEW);
openLinkInBrowser.setData(Uri.parse(mEventUrl));
startActivity(openLinkInBrowser);
} else {
Toast.makeText(MainActivity.this, "Links are not provided", Toast.LENGTH_SHORT).show();
}
}
});
loveBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (status) {
Toast.makeText(MainActivity.this, "Liked", Toast.LENGTH_SHORT).show();
mEventsObject.setHeartLiked(true);
} else {
Toast.makeText(MainActivity.this, "Disliked", Toast.LENGTH_SHORT).show();
mEventsObject.setHeartLiked(false);
}
}
});
return convertView;
}
