我想在使用GridView显示的相对布局示例中更改textview的颜色，我想要更改textview的颜色，该颜色位于网格项目单击其位置的relaytivelayout内部。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/rel_bg"
android:layout_width="60dp"
android:layout_height="30dp"
android:background="@drawable/grid_item_bg"
android:orientation="vertical">

<TextView
    android:textColor="@drawable/state_rel"
    android:id="@+id/bTxt"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"

In the .java file, very like acitvity_main:

在.java文件中，非常像acitvity_main：

First you have to initialize your TextView by saying: TextView myTextView = (TextView) findViewById(R.id.myid);

首先，您必须通过以下方式初始化TextView：TextView myTextView =（TextView）findViewById（R.id.myid）;

Than you can simply say: myTextView.setBackGroundColor(Color.argb(x1,x2,x3,x4);

比你可以简单地说：myTextView.setBackGroundColor（Color.argb（x1，x2，x3，x4）;

x1 - x4 can get a value from 0 to 250. 0 is very light, 250 is very dark.

x1 - x4可以得到0到250之间的值.0非常轻，250非常暗。

x1 = the opacity;

x1 =不透明度;

x2 = red;

x2 =红色;

x3 = green;

x3 =绿色;

x4 = blue;

x4 =蓝色;

An example: myTextView.setBackgroundColor(Color.argb(250,250,0,0); would set a very red Background.

例如：myTextView.setBackgroundColor（Color.argb（250,250,0,0）;会设置一个非常红的背景。
