实现的效果，是一个滚动的公告栏，是这样的：
可以看到这个公告栏一方面是滚动，另外一方面是可点击。
实现的思路：
1.textView放在ViewFlipper中实现滑动效果（可设置左右、或者上下滚动），很明显这应该是自定义view；
2.利用textView的点击事件即可实现点击；
OK，先看看自定义view的代码：
public class MarqueeTextView extends LinearLayout { private Context mContext; private ViewFlipper viewFlipper; private View marqueeTextView; private String[] textArrays; private MarqueeTextViewClickListener marqueeTextViewClickListener; public MarqueeTextView(Context context) { super(context); mContext = context; initBasicView(); } public MarqueeTextView(Context context, AttributeSet attrs) { super(context, attrs); mContext = context; initBasicView(); } public void setTextArraysAndClickListener(String[] textArrays, MarqueeTextViewClickListener marqueeTextViewClickListener) {//1.设置数据源；2.设置监听回调（将textView点击事件传递到目标界面进行操作） this.textArrays = textArrays; this.marqueeTextViewClickListener = marqueeTextViewClickListener; initMarqueeTextView(textArrays, marqueeTextViewClickListener); } public void initBasicView() {//加载布局，初始化ViewFlipper组件及效果 marqueeTextView = LayoutInflater.from(mContext).inflate(R.layout.marquee_textview_layout, null); LayoutParams layoutParams = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT); addView(marqueeTextView, layoutParams); viewFlipper = (ViewFlipper) marqueeTextView.findViewById(R.id.viewFlipper); viewFlipper.setInAnimation(AnimationUtils.loadAnimation(mContext, R.anim.slide_in_bottom));//设置上下的动画效果（自定义动画，所以改左右也很简单） viewFlipper.setOutAnimation(AnimationUtils.loadAnimation(mContext, R.anim.slide_out_top)); viewFlipper.startFlipping(); } public void initMarqueeTextView(String[] textArrays, MarqueeTextViewClickListener marqueeTextViewClickListener) { if (textArrays.length == 0) { return; } int i = 0; viewFlipper.removeAllViews(); while (i < textArrays.length) { TextView textView = new TextView(mContext); textView.setText(textArrays[i]); textView.setOnClickListener(marqueeTextViewClickListener); LayoutParams lp = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT); viewFlipper.addView(textView, lp); i++; } } public void releaseResources() { if (marqueeTextView != null) { if (viewFlipper != null) { viewFlipper.stopFlipping(); viewFlipper.removeAllViews(); viewFlipper = null; } marqueeTextView = null; } } }
然后，主Activity异常简单（还是封装得好）：
public class MainActivity extends AppCompatActivity { private MarqueeTextView marqueeTv; private String [] textArrays = new String[]{"this is content No.1","this is content No.2","this is content No.3"}; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); marqueeTv = (MarqueeTextView) findViewById(R.id.marqueeTv); marqueeTv.setTextArraysAndClickListener(textArrays, new MarqueeTextViewClickListener() { @Override public void onClick(View view) { startActivity(new Intent(MainActivity.this,AnotherActivity.class)); } }); } @Override protected void onDestroy() { marqueeTv.releaseResources(); super.onDestroy(); } }
