我想知道在单击或触摸文本视图后，是否可以更改颜色。文件中有多个文本视图，我想知道在选择某个文本视图时我需要做什么。目前我只能改变
的颜色这是我的代码？
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_image);
ImageView image = (ImageView) findViewById(R.id.imageView1);
SeekBar sliderBar = (SeekBar) findViewById(R.id.sliderBar);
paint = new Paint();
paint.setColor(Color.RED);
sliderBar.setProgress(-3);
sliderBar.incrementProgressBy(1);
sliderBar.setMax(6);
category1 = (TextView) findViewById(R.id.category1);
category2 = (TextView) findViewById(R.id.category2);
category3 = (TextView) findViewById(R.id.category3);
category4 = (TextView) findViewById(R.id.category4);
category5 = (TextView) findViewById(R.id.category5);
category6 = (TextView) findViewById(R.id.category6);
category7 = (TextView) findViewById(R.id.category7);
category8 = (TextView) findViewById(R.id.category8);
category9 = (TextView) findViewById(R.id.category9);
textProgress = (TextView) findViewById(R.id.sliderText);
category1.setClickable(true);
category2.setClickable(true);
category3.setClickable(true);
category4.setClickable(true);
category5.setClickable(true);
category6.setClickable(true);
category7.setClickable(true);
category8.setClickable(true);
category9.setClickable(true);
sliderBar.setOnSeekBarChangeListener(new OnSeekBarChangeListener()
{
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser)
{
// TODO Auto-generated method stub
textProgress.setText("The value is: "+ (-3+progress) );
if(progress ==0) //slider is at -3
{
if(category1.isSelected())
{
category1.setTextColor(Color.BLUE);
}
if(category2.isSelected())
{
category2.setTextColor(Color.BLUE);
}
}
else if(progress==1) //slider is at -2
{
category1.setTextColor(Color.BLACK);
}
else if(progress==2) //slider is at -1
{
category1.setTextColor(Color.BLUE);
}
else if (progress==3) //slider is at 0
{
category1.setTextColor(Color.BLACK);
}
else if (progress==4) //slider is at 1
{
category1.setTextColor(Color.DKGRAY);
}
else if (progress==5) //slider is at 2
{
category1.setTextColor(Color.MAGENTA);
}
else if (progress==6) //slider is at 3
{
category1.setTextColor(Color.RED);
}
}
public void onStartTrackingTouch(SeekBar arg0) {
// TODO Auto-generated method stub
}
public void onStopTrackingTouch(SeekBar arg0) {
// TODO Auto-generated method stub
}
});
}
我想知道当我选择不同的类别时，我可以使用搜索栏更改文本的颜色，但只选择textview（类别“X”）的颜色。谢谢。
