ScrollingMovementMethod（）问题

Question

因此，对于大文本，我使用ScrollingMovementMethod（）。但是有一个问题，当按下文本滚动时，文本变为灰色。可以修复吗？

的.java

public class Knowledge extends Activity {
Button back, newText;
TextView TVHeading, TV;

void newText() {
    Random rand = new Random();
    int n = rand.nextInt(10) + 1;
    String text = "knw" + n;
    String resourceId = getResources().getString(
            getResources().getIdentifier(text, "string", getPackageName()));
    String[] knowledgeArray = resourceId.split("\n");
    TVHeading.setText(knowledgeArray[0]);
    TV.setText(knowledgeArray[1]);
}

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.knowledge);
    back = (Button) findViewById(R.id.backKnowledge);
    newText = (Button) findViewById(R.id.newText);
    TVHeading = (TextView) findViewById(R.id.knowledgeTVHeading);
    TV = (TextView) findViewById(R.id.knowledgeTV);
    TV.setMovementMethod(new ScrollingMovementMethod());
    newText();
    back.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            finish();
        }
    });
    newText.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            newText();
        }
    });
}

}

尝试为textView属性使用纯色，如下所示：

android:textColor="#000000"
android:textColorHighlight="#000000"
