因为我在许多活动屏幕中需要相同的按钮,我已经扩展了按钮来创建一个RachelButton,并且我在构造函数中设置它.

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
        }
    });
}

那么我用来生成彩色按钮的资源就是这样的：

<?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" />
    </shape>
</item>

<item android:state_focused="true" >
    <shape>
        <gradient
            android:endColor="@color/info_normal"
            android:startColor="@color/info_normal"
            android:angle="270" />
        <stroke
            android:width="3dp"
            android:color="@color/info_normal" />
        <corners
            android:radius="3dp" />
        <padding
            android:left="5dp"
            android:top="5dp"
            android:right="5dp"
            android:bottom="5dp" />
    </shape>
</item>

<item>
    <shape>
        <gradient
            android:endColor="@color/info_normal"
            android:startColor="@color/info_normal"
            android:angle="270" />
        <stroke
            android:width="3dp"
            android:color="@color/info_normal" />
        <corners
            android:radius="3dp" />
        <padding
            android:left="5dp"
            android:top="5dp"
            android:right="5dp"
            android:bottom="5dp" />
    </shape>
</item>
</selector>

正如您可以在代码中看到的,我设置文本颜色,我确信这种颜色作为一种资源(谢谢IntelliJ).

但是设置这样的文本颜色根本没有任何效果,按钮上的文本颜色似乎是按钮背景颜色的阴影.

如果有人可以给我一些关于接下来要尝试的建议,我将是最感激的.
