配置方法：

project中build.gradle檔案內:

allprojects {
          repositories {
             ...
             maven { url "https://jitpack.io" }
          }
       }

module中build.gradle新增依賴:

dependencies {
             compile 'com.github.paradoxie:AutoVerticalTextview:0.1' 
    }

使用方法：

1、自定義view：

package cn.wdf.textview_roll;
 
import android.content.Context;
import android.graphics.Color;
import android.os.Handler;
import android.os.Message;
import android.util.AttributeSet;
import android.view.Gravity;
import android.view.View;
import android.view.animation.AccelerateInterpolator;
import android.view.animation.Animation;
 
import android.view.animation.TranslateAnimation;
import android.widget.TextSwitcher;
import android.widget.TextView;
import android.widget.ViewSwitcher;import java.util.ArrayList;
public class VerticalTextview extends TextSwitcher implements ViewSwitcher.ViewFactory {

    private static final int 
 
FLAG_START_AUTO_SCROLL = 0;
    private static final int FLAG_STOP_AUTO_SCROLL = 1;
    private float mTextSize = 16;
    private int mPadding = 5;
    private int textColor = Color.GREEN;
/**
     * @param textSize  字號
     * @param padding   內邊距
     * @param textColor 字型顏色
     */
public void setText(float textSize, int padding, int textColor) {
        mTextSize = textSize;
mPadding = padding;
        this.textColor = textColor;
}

    private OnItemClickListener itemClickListener;
    private Context mContext;
    private int currentId = -1;
    private ArrayList<String> textList;
    private Handler handler;
    public VerticalTextview(Context context) {
        this(context, null);
mContext = context;
}

    public VerticalTextview(Context context, AttributeSet attrs) {
        super(context, attrs);
mContext = context;
textList = new ArrayList<String>();
}

    public void setAnimTime(long animDuration) {
        setFactory(this);
Animation in = new TranslateAnimation(0, 0, animDuration, 0);
in.setDuration(animDuration);
in.setInterpolator(new AccelerateInterpolator());
Animation out = new TranslateAnimation(0, 0, 0, -animDuration);
out.setDuration(animDuration);
out.setInterpolator(new AccelerateInterpolator());
setInAnimation(in);
setOutAnimation(out);
}

    /**
     * 間隔時間
     *
     * @param time
*/
public void setTextStillTime(final long time) {
        handler = new Handler() {
            @Override
public void handleMessage(Message msg) {
                switch (msg.what) {
                    case FLAG_START_AUTO_SCROLL:
                        if (textList.size() > 0) {
                            currentId++;
setText(textList.get(currentId % textList.size()));
}
                        handler.sendEmptyMessageDelayed(FLAG_START_AUTO_SCROLL, time);
                        break;
                    case FLAG_STOP_AUTO_SCROLL:
                        handler.removeMessages(FLAG_START_AUTO_SCROLL);
                        break;
}
            }
        };
}

    /**
     * 設定資料來源
     *
     * @param titles
*/
public void setTextList(ArrayList<String> titles) {
        textList.clear();
textList.addAll(titles);
currentId = -1;
}

    /**
     * 開始滾動
     */
public void startAutoScroll() {
        handler.sendEmptyMessage(FLAG_START_AUTO_SCROLL);
}

    /**
     * 停止滾動
     */
public void stopAutoScroll() {
        handler.sendEmptyMessage(FLAG_STOP_AUTO_SCROLL);
}

    @Override
public View makeView() {
        TextView t = new TextView(mContext);
t.setGravity(Gravity.CENTER_VERTICAL | Gravity.LEFT);
t.setMaxLines(1);
t.setPadding(mPadding, 0, 0, 0);
t.setTextColor(textColor);
t.setTextSize(mTextSize);
t.setClickable(true);
t.setOnClickListener(new OnClickListener() {
            @Override
public void onClick(View v) {
                if (itemClickListener != null && textList.size() > 0 && currentId != -1) {
                    itemClickListener.onItemClick(currentId % textList.size());
}
            }
        });
        return t;
}

    /**
     * 設定點選事件監聽
     *
     * @param itemClickListener
*/
public void setOnItemClickListener(OnItemClickListener itemClickListener) {
        this.itemClickListener = itemClickListener;
}

    /**
     * 輪播文字點選監聽器
     */
public interface OnItemClickListener {
        /**
         * 點選回撥
         *
         * @param position 當前點選ID
         */
void onItemClick(int position);
}

}

2、xml佈局：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="cn.wdf.textview_roll.MainActivity">
<cn.wdf.textview_roll.VerticalTextview
android:id="@+id/mTv"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ffff"
/>
</RelativeLayout>

3、activity中：

在這個類中可以設定字型的大小、顏色和內邊距。設定每行TextView停留時長間隔，設定進入和退出的時間間隔。

package cn.wdf.textview_roll;
import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.widget.Toast;
import java.util.ArrayList;
public class MainActivity extends Activity {
    private VerticalTextview TextView;
    private ArrayList<String> titleList= new ArrayList<String>();
@Override
protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
init();
}

    private void init() {
        TextView=findViewById(R.id.mTv);
titleList.add("熬過最難熬的那段時間");
titleList.add("你擦乾眼淚終於明白");
titleList.add("有些人");
titleList.add("註定是讓你成長的");
titleList.add("正如");
titleList.add("至尊寶在離開紫霞仙子後");
titleList.add("才真正成長為孫悟空一樣");
TextView.setTextList(titleList);
TextView.setText(22, 50, Color.RED);//設定屬性
TextView.setTextStillTime(3000);//設定停留時長間隔
TextView.setAnimTime(1000);//設定進入和退出的時間間隔
TextView.setOnItemClickListener(new VerticalTextview.OnItemClickListener() {
            @Override
public void onItemClick(int position) {
                Toast.makeText(MainActivity.this,"點選了："+titleList.get(position),Toast.LENGTH_SHORT).show();
}
        });
}

    @Override
protected void onResume() {
        super.onResume();
TextView.startAutoScroll();
}

    @Override
protected void onPause() {
        super.onPause();
TextView.stopAutoScroll();
}
}
