在ArrayAdapter的ListView的Andr​​oid更改特定的行 [英] Change a specific row in a ArrayAdapter ListView Android

问题描述

我试图改变依赖于不同状态的特定行的颜色。这是code I具有的时刻。

I am trying to change the color on a specific row depending on different states. This is the code i have at the moment.

 public View getView(int position, View convertView, ViewGroup parent) {

  View row=convertView;

     if (row==null) {                                                    
         LayoutInflater inflater=getLayoutInflater();

         row=inflater.inflate(R.layout.doit, parent, false);
     }

     TextView label = (TextView) row.findViewById(R.id.mess);

     label.setText(ArrayAdapter.getItem(position));

     switch(mState){
     case STATE1:

      label.setTextColor(Color.WHITE);
      break;
     case STATE2:
      label.setTextColor(Color.BLACK);
      break;
     case STATE3:
      label.setTextColor(Color.YELLOW);
      break;
     }


     return(row);
 }

}

在code还挺works..but它改变了所有行。任何想法？

The code kinda works..but it changes all the rows. Any ideas?

推荐答案

因此​​Android每个重用，这就是为什么你看到它影响所有行的时间观。你需要做的是明确设定了每种情况的颜色。这样将其设置到任何你默认布局中默认情况也许添加到您的switch语句？

so android reuses the View each time that's why you're seeing it affect all the rows. What you need to do is explicitly set the color for each case. perhaps add a 'default' case to your switch statement so that it sets it to whatever you're default is in the layout?
