检查动态添加的复选框的状态 [英] Check the state of checkboxes which were added dynamically

问题描述

我以如下方式动态添加我的复选框:

I add my checkboxes dynamically like this:

 public void addFiles()
        {

             LinearLayout layout = (LinearLayout) findViewById(R.id.filesList);

            if(!FileManagerActivity.finalAttachFiles.isEmpty())
            {   

                for (final File file:FileManagerActivity.finalAttachFiles)
                {   

                    Log.i("what I've got", file.toString());
                    View line = new View(this);
                    line.setLayoutParams(new LayoutParams(1, LayoutParams.MATCH_PARENT));
                    line.setBackgroundColor(0xAA345556);
                    informationView= new CheckBox(this);
                    informationView.setTextColor(Color.BLACK);
                    informationView.setTextSize(16);
                    informationView.setGravity(Gravity.CENTER_VERTICAL | Gravity.CENTER_HORIZONTAL);
                    informationView.setCompoundDrawablesWithIntrinsicBounds(R.drawable.file_icon, 0, 0, 0);
                    informationView.setText(file.getName().toString());
                    layout.addView(informationView, 0);
                    layout.addView(line, 1);
                    layout.postInvalidate();


                }
            }

        }

我有一个按钮，该onClick事件应获取那些复选框的可检查状态，并删除已选中的复选框...我该如何实现呢?

And I have a button, which onClick event should get the checkable state of those checkboxes and delete which were checked...How can I implement this?

推荐答案

您可以添加以下复选框:

your can add your checkboxes like:

for(int i=0;i<totalCB;i++){
    CheckBox chB=new CheckBox(context);
    ...
    chB.setId(i);
    layout.add(...);// add checkbox to view
}

现在，点击按钮

for(int i=0;i<totalCB;i++){
    CheckBox cb=(CheckBox)findViewById(i);
    boolean checked=cd.isChecked();// status of checkbox

    if(checked){
       // perform action 
    }
}
