android 滚动textview

实现textview 自动滚动，不需要焦点事件

java 代码, 自定义textview

import android.content.Context;
import android.util.AttributeSet;

import androidx.annotation.NonNull;
import androidx.annotation.Nullable;
import androidx.appcompat.widget.AppCompatTextView;

public class MyTextView extends AppCompatTextView {
    public MyTextView(@NonNull Context context) {
        super(context);
    }

    public MyTextView(@NonNull Context context, @Nullable AttributeSet attrs) {
        super(context, attrs);
    }

    public MyTextView(@NonNull Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    public boolean isFocused() {
        return true;
    }
}

xml调用

  <com.zhj.freetv.view.MyTextView
        android:id="@+id/tv_name"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:ellipsize="marquee"
        android:gravity="center"
        android:includeFontPadding="false"
        android:textColor="#FFFFFF"
        android:singleLine="true"
        android:focusable="true"
        android:padding="10dp"
        android:marqueeRepeatLimit="marquee_forever"
        android:textSize="16sp" />
