垂直滚动广告条

1、效果图如下

效果图

1. 每条广告一行显示，过长则末尾显示省略号；
2. 点击每条广告执行相应的动作；
3. 左侧添加一个固定的图标

2.布局代码如下

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:paddingLeft="20dp"
    android:paddingRight="20dp"
    android:orientation="horizontal"
    tools:context=".MainActivity">

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@mipmap/ic_launcher"/>

    <com.hyz.shaoyang.vertexttest.VerticalTextView
        android:id="@+id/tvVerText"
        android:layout_marginLeft="10dp"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical" />
</LinearLayout>

3、垂直滚动控件代码

参考自垂直滚动控件

import android.content.Context;
import android.os.Handler;
import android.os.Message;
import android.text.TextUtils;
import android.util.AttributeSet;
import android.view.View;
import android.view.View.OnClickListener;
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.ViewFactory;
import java.util.ArrayList;

public class VerticalTextView extends TextSwitcher implements ViewFactory {
    private static final int FLAG_START_AUTO_SCROLL = 0;
    private static final int FLAG_STOP_AUTO_SCROLL = 1;
    private float mTextSize;
    private int mPadding;
    private int textColor;
    private VerticalTextView.OnItemClickListener itemClickListener;
    private Context mContext;
    private int currentId;
    private ArrayList<String> textList;
    private Handler handler;

    public void setText(float textSize, int padding, int textColor) {
        this.mTextSize = textSize;
        this.mPadding = padding;
        this.textColor = textColor;
    }

    public VerticalTextView(Context context) {
        this(context, (AttributeSet)null);
        this.mContext = context;
    }

    public VerticalTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        this.mTextSize = 16.0F;
        this.mPadding = 5;
        this.textColor = -16777216;
        this.currentId = -1;
        this.mContext = context;
        this.textList = new ArrayList();
    }

    public void setAnimTime(long animDuration) {
        this.setFactory(this);
        Animation in = new TranslateAnimation(0.0F, 0.0F, (float)animDuration, 0.0F);
        in.setDuration(animDuration);
        in.setInterpolator(new AccelerateInterpolator());
        Animation out = new TranslateAnimation(0.0F, 0.0F, 0.0F, (float)(-animDuration));
        out.setDuration(animDuration);
        out.setInterpolator(new AccelerateInterpolator());
        this.setInAnimation(in);
        this.setOutAnimation(out);
    }

    public void setTextStillTime(final long time) {
        this.handler = new Handler() {
            public void handleMessage(Message msg) {
                switch(msg.what) {
                    case 0:
                        if (VerticalTextView.this.textList.size() > 0) {
                            VerticalTextView.this.currentId++;
                            VerticalTextView.this.setText((CharSequence)VerticalTextView.this.textList.get(VerticalTextView.this.currentId % VerticalTextView.this.textList.size()));
                        }

                        VerticalTextView.this.handler.sendEmptyMessageDelayed(0, time);
                        break;
                    case 1:
                        VerticalTextView.this.handler.removeMessages(0);
                }

            }
        };
    }

    public void setTextList(ArrayList<String> titles) {
        this.textList.clear();
        this.textList.addAll(titles);
        this.currentId = -1;
    }

    public void startAutoScroll() {
        this.handler.sendEmptyMessage(0);
    }

    public void stopAutoScroll() {
        this.handler.sendEmptyMessage(1);
    }

    public View makeView() {
        TextView t = new TextView(this.mContext);
        t.setGravity(19);
        t.setMaxLines(1);
        t.setPadding(this.mPadding, this.mPadding, this.mPadding, this.mPadding);
        t.setTextColor(this.textColor);
        t.setTextSize(this.mTextSize);
       //  此处添加了右侧省略号效果
        t.setEllipsize(TextUtils.TruncateAt.END);
        t.setClickable(true);
        t.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                if (VerticalTextView.this.itemClickListener != null && VerticalTextView.this.textList.size() > 0 && VerticalTextView.this.currentId != -1) {
                    VerticalTextView.this.itemClickListener.onItemClick(VerticalTextView.this.currentId % VerticalTextView.this.textList.size());
                }

            }
        });
        return t;
    }

    public void setOnItemClickListener(VerticalTextView.OnItemClickListener itemClickListener) {
        this.itemClickListener = itemClickListener;
    }

    public interface OnItemClickListener {
        void onItemClick(int var1);
    }
}

稍微改了下：添加了右侧省略号效果。

4、关键代码：

public class MainActivity extends AppCompatActivity {

    private VerticalTextView    mTvVerText;
    private ArrayList<String>   mTitleList = new ArrayList<String>();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        initADList();
        mTvVerText = findViewById(R.id.tvVerText);
        mTvVerText.setTextList(mTitleList);
        mTvVerText.setText(18, 5, Color.RED);
        mTvVerText.setTextStillTime(3000);
        mTvVerText.setAnimTime(300);
        //对单条文字的点击监听
        mTvVerText.setOnItemClickListener(new VerticalTextView.OnItemClickListener() {
            @Override
            public void onItemClick(int position) {
                Toast.makeText(MainActivity.this, mTitleList.get(position), Toast.LENGTH_SHORT).show();
            }
        });

    }


    private void initADList(){
        mTitleList.add("第一条广告第一条广告第一条广告第一条广告第一条广告");
        mTitleList.add("第二条广告第二条广告第二条广告第二条广告第二条广告");
        mTitleList.add("第三条广告第三条广告第三条广告第三条广告第三条广告");
        mTitleList.add("第四条广告第四条广告第四条广告第四条广告第四条广告");

    }

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

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