java - 如何为动态创建的 TextView 设置点击功能？

Question

好的，所以我想动态创建一个 TextView ，然后在单击该 TextView 后我去运行一个函数。这是我的代码

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data){
        super.onActivityResult(requestCode, resultCode, data);
        Bundle bundle = data.getExtras();
        contacts.add(bundle);
        String fname = bundle.getString("fname");
        LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
        LinearLayout layout = (LinearLayout) findViewById(R.id.contactList);

        TextView textView = new TextView(this);
        textView.setLayoutParams(params);
        textView.setText(fname);
        textView.setId(idCounter);
        textView.setOnClickListener(showDetails());
        layout.addView(textView);

    }

这是我想调用的函数

public void showDetails(View view){
        //create intent
        //get id of textview
        //get bundle object for that textview
        //send bundle object to new activity
        //start new activity

    }

如何让 TextView 在单击 TextView 时调用 showDetails？

Answer 1

您必须将 View.OnClickListener 实例传递给 setOnClickListener:

View.OnClickListener listener = view -> {
    showDetails();
};
textView.setOnClickListener(listener);
