启动自定义对话框，用于在列表视图的OnClickListener中单击某个位置

// 假设你已经有一个ListView实例和一个适配器
ListView listView = findViewById(R.id.listView);
listView.setAdapter(adapter);

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        // 创建自定义对话框
        AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
        LayoutInflater inflater = getLayoutInflater();
        View dialogView = inflater.inflate(R.layout.custom_dialog, null);
        builder.setView(dialogView);

        // 设置对话框中的按钮和事件
        Button btnConfirm = dialogView.findViewById(R.id.btn_confirm);
        btnConfirm.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // 处理确认操作
                Toast.makeText(MainActivity.this, "Confirmed!", Toast.LENGTH_SHORT).show();
                dialog.dismiss();
            }
        });

        AlertDialog dialog = builder.create();
        dialog.show();
