添加删除选项动态生成EDITTEXT [英] Add delete option with dynamically generated editText

问题描述

我在Android的新的和我有以下code创建EDITTEXT动态的同时单击添加新button.Is可以添加删除按钮EDITTEXT附近，这样每个同时单击删除相应EDITTEXT将被删除？

  btnAddNew.setOnClickListener（新OnClickListener（）{        公共无效的onClick（视图v）{            的LinearLayout rAlign =（的LinearLayout）findViewById（R.id.lId）;
            的EditText newPass =新的EditText（getApplicationContext（））;
            allEds.add（newPass）;
            newPass.setHint（标签名称）;
            newPass.setLayoutParams（新的LayoutParams（LayoutParams.WRAP_CONTENT，LayoutParams.WRAP_CONTENT））;
            newPass.setWidth（318）;
            newPass.setTextColor（Color.parseColor（＃333333））;
            newPass.setId（TEXTB）;            rAlign.addView（newPass）;
            MY_BUTTON ++;
            addSpinner（）;
        }
    }）;
 

解决方案

是的，在同一时间，因为你的EditText创建删除按钮并使用 removeView（）方法就像 addView（）方法，也许是这样的：

  btnAddNew.setOnClickListener（新OnClickListener（）{
    公共无效的onClick（视图v）{
        ...
        rAlign.addView（newPass）;
        MY_BUTTON ++;
        addSpinner（）;        按钮btnRemoveOld =新按钮（本）;
        btnRemoveOld.setId（32）; //任意数量
        btnRemoveOld.setOnClickListener（新OnClickListener（）{
            公共无效的onClick（视图v）{
                的LinearLayout rAlign =（的LinearLayout）findViewById（R.id.lId）;
                rAlign.removeView（findViewById（TEXTB））;
            }
        }）;        //你将需要设置参数来定义如何按钮看起来
        //以及它是相对于的EditText这里
        rAlign.addView（btnRemoveOld）;
    }
}）;
 

I'm new in android and i have created editText dynamically with the following code while clicking add new button.Is it possible to add a delete button near editText so that each while clicking the delete respective editText will be removed?

btnAddNew.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {

            LinearLayout rAlign = (LinearLayout)findViewById(R.id.lId);
            EditText newPass = new EditText(getApplicationContext());
            allEds.add(newPass);
            newPass.setHint("Name of Label");
            newPass.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
            newPass.setWidth(318);
            newPass.setTextColor(Color.parseColor("#333333"));
            newPass.setId(textb);

            rAlign.addView(newPass);
            MY_BUTTON ++;               
            addSpinner();               
        }
    });

解决方案

Yes, create your remove button at the same time as your EditText and use the removeView() method just like the addView() method, maybe like this:

btnAddNew.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
        ...
        rAlign.addView(newPass);
        MY_BUTTON ++;               
        addSpinner();

        Button btnRemoveOld = new Button(this);
        btnRemoveOld.setId(32); // arbitrary number
        btnRemoveOld.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                LinearLayout rAlign = (LinearLayout)findViewById(R.id.lId);
                rAlign.removeView(findViewById(textb));
            }
        });     

        // You will need to set parameters to define how the button looks
        //   and where it is in relation to the EditText here
        rAlign.addView(btnRemoveOld);
    }
});
