有一个简单的解决方案：

  private static TextView selectedView = null; 

 ... ... 

 eachTextView.setOnClickListener（new View.OnClickListener（）{

 @Override 
 public void onClick （View v）{

 //将上次选择的视图更改为正常
 if（selectedView！= null）
 selectedView.setTextColor（Color.parseColor（＃D8000000） ）; 

 //将selectedView设置为当前所选视图
 selectedView =（TextView）v; 

 //将所选视图更改为红色
 selectedView.setTextColor（Color.parseColor（＃FF0000））; 



 Toast.makeText（getActivity（），toppings！，
 Toast。 LENGTH_LONG）.show（）; 
} 

}）; 
 

如果你想改变TextView的背景颜色insdead文本颜色，那么只需将'setTextColor' setBackgroundColor'。

除了你的情况，似乎不是必须使用选择器，因为它只是为特定的视图状态变化，与其他视图无关。 / p>

I have 3 text views as shown below. once i click on one of it, now it turns to red and turn backs to its default colour. I want to keep the selected textview in red. i have these 3 textview in a fragment.

mQuickReturnView = (TextView) view.findViewById(R.id.footer);
        mQuickReturnView1 = (TextView) view.findViewById(R.id.footer1);
        mQuickReturnView2 = (TextView) view.findViewById(R.id.footer2);

        TextView clickTextView = (TextView) view.findViewById(R.id.footer);
        TextView clickTextView1 = (TextView) view.findViewById(R.id.footer1);
        TextView clickTextView2 = (TextView) view.findViewById(R.id.footer2);

        clickTextView.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {

                Toast.makeText(getActivity(), "toppings!",
                        Toast.LENGTH_LONG).show();
            }

        });
        clickTextView1.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {

                Toast.makeText(getActivity(), "Bigg pizza!",
                        Toast.LENGTH_LONG).show();
            }

        });
        clickTextView2.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {

                Toast.makeText(getActivity(), "Italiano!",
                        Toast.LENGTH_LONG).show();
            }

        });

There is one simple solution:

private static TextView selectedView = null;

... ...

eachTextView.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {

            //change last selected view to be normal
            if(selectedView != null)
                 selectedView.setTextColor(Color.parseColor("#D8000000"));

            //set selectedView to be current selected view
            selectedView = (TextView)v;

            //change selected view to be red
            selectedView.setTextColor(Color.parseColor("#FF0000"));



            Toast.makeText(getActivity(), "toppings!",
                    Toast.LENGTH_LONG).show();
        }

    });

If you want to change TextView background color insdead of text color, then just replace 'setTextColor' with 'setBackgroundColor'.

Besides for your case, seems it is not neccessary to use selector, because it is just for specific view state change, nothing to do with other view.
