如果该按钮的当前文字颜色为红色,我想检查按钮点击事件吗?
到目前为止我已经这样做了:
ColorStateList mList = gridcell.getTextColors();
int col=mList.getDefaultColor();
switch(col)
{
case Color.RED:
Toast.makeText(getApplicationContext(), "RED",
Toast.LENGTH_SHORT).show();
break;
}
但是当我点击文本颜色为红色的按钮时,它会干任何东西,defaut颜色为白色,并且在所有te按钮中变为白色。我现在能做什么?

试试这个:
Button button=(Button) findViewById(R.id.b);
button.setTextColor(Color.RED);
button.setOnClickListener(this);
按钮的点击事件:
public void onClick(View v) {
if(button.getCurrentTextColor()==Color.RED){
Toast.makeText(getBaseContext(), "Red", Toast.LENGTH_SHORT).show();
}
}
