推荐答案

对不起，我的朋友耽搁了.必须解决您的问题，这需要一段时间.所以首先是输出，

Hey sorry for the delay my friend. Had to work on your problem and it took a while. So first goes the output,

所以假设上面显示的是您需要的输出，这里是它的代码.

So assuming that the above shown is your needed output here is the code to it.

xml 文件

<TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:text="@string/hello_world"/>

res 文件(比如 strings.xml)

<color  name="violet">#9400D3</color>
<color  name="indigo">#4B0082</color>
<color  name="blue">#0000FF</color>
<color  name="green">#00FF00</color>
<color  name="yellow">#FFFF00</color>
<color  name="orange">#FF7F00</color>
<color  name="red">#FF0000</color>

您的 java 文件

     TextView textView = (TextView)findViewById(R.id.textView1);
        Shader textShader=new LinearGradient(0, 0, 0, 20,
                new int[]{getResources().getColor(R.color.violet),getResources().getColor(R.color.indigo),
                getResources().getColor(R.color.blue),
                getResources().getColor(R.color.green),
                getResources().getColor(R.color.yellow),
                getResources().getColor(R.color.orange),
                getResources().getColor(R.color.red)},
                new float[]{0,0.2f,0.4f,0.6f,0.8f,0.9f,1}, TileMode.CLAMP);
        textView.getPaint().setShader(textShader);
        textView.setTextSize(20);
