我已經(jīng)使用ViewFlipper控件來(lái)顯示從左到右連續(xù)間隔的推文.我在ViewFlipper中為每條推文添加了動(dòng)態(tài)textview.

一切都很好,但有時(shí)textview重疊.

什么是這種奇怪行為的原因？

碼：

for (int i = 0; i < tweets.length(); i++) {

tweet = tweets.getJSONObject(i).getString("title")+"?? tweet on ?"+tweets.getJSONObject(i).getString("pubDate");

tv = new TextView(context);

LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(

LayoutParams.WRAP_CONTENT, LayoutParams.FILL_PARENT);

params.weight = 1.0f;

params.gravity=48;

tv.setLayoutParams(params);

tv.setGravity(Gravity.CENTER);

tv.setTextSize(22);

tv.setTextColor(ColorStateList.valueOf(Color.WHITE));

tv.setSingleLine();

//tv.setTextColor(getREs)

tv.setText(tweet);

flipper.addView(tv);

}

flipper.setInAnimation(inFromRightAnimation(1500));

flipper.setOutAnimation(outToLeftAnimation(1500));

flipper.startFlipping();

public static Animation inFromRightAnimation(int duration) {

Animation inFromRight = new TranslateAnimation(

Animation.RELATIVE_TO_PARENT, +1.0f, Animation.RELATIVE_TO_PARENT, 0.0f,

Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, 0.0f

);

inFromRight.setDuration(duration);

inFromRight.setInterpolator(new AccelerateInterpolator());

return inFromRight;

}

public static Animation outToLeftAnimation(int duration) {

Animation outtoLeft = new TranslateAnimation(

Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, -1.0f,

Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, 0.0f

);

outtoLeft.setDuration(duration);

outtoLeft.setInterpolator(new AccelerateInterpolator());

return outtoLeft;

}

編輯：

這是另一個(gè)顯示上述問(wèn)題的快照..

總結(jié)
