状态改变时我需要改变文字颜色(按下,对焦)......

如何设置的文本颜色TextView使用ColorsStateList？

编辑,解决:

textView.setTextColor(new ColorStateList(
   new int [] [] {
      new int [] {android.R.attr.state_pressed},
      new int [] {android.R.attr.state_focused},
      new int [] {}
   },
   new int [] {
      Color.rgb (255, 128, 192),
      Color.rgb (100, 200, 192),
      Color.White
   }
));

解决方案2

textView.setTextColor(getResources().getColorStateList(R.color.your_colors))

单击时更改TextView的背景颜色

我正在从REST API中读取一些数据,需要根据应用程序收到的信息生成一些按钮.

因为我在许多Activity屏幕中需要相同的按钮,所以我扩展了Button来制作一个RachelButton并在构造函数中进行设置.

public RachelButton(Context context, Info info) {
    super(context);
    this.info= info;

    setText(info.getTime());
    setTypeface(Typeface.DEFAULT, Typeface.BOLD);

    int identifier = 0;

    if(info.isAvailable()){
        identifier = getContext().getResources().getIdentifier("drawable/info_button_"+info.getType(), null, getContext().getPackageName());
    }else{
        identifier = R.drawable.info_button_unavailable;
    }

    if(identifier == 0){
        Log.e("INFO_BUTTON", "no button for "+info.getType());
    }

    setBackgroundResource(identifier);
    setTextColor(R.color.info_button_text_color);

    setOnClickListener(new View.OnClickListener(){
        public void onClick(View view) {
            //do stuff
        }
    });
}

然后我用来生成彩色按钮的资源示例如下:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" >
    <shape>
        <gradient
            android:startColor="@color/button_pressed"
            android:endColor="@color/button_pressed"
            android:angle="270" />
        <stroke
            android:width="3dp"
            android:color="@color/button_pressed" />
        <corners
            android:radius="3dp" />
        <padding
            android:left="5dp"
            android:top="5dp"
            android:right="5dp"
            android:bottom="5dp" …
