Question

我正在开发聊天应用程序。我正面临listview奇怪的行为问题。 我的代码在Android OS 4.4下完美运行。但是当我在4.4 kitkat中运行我的应用程序时，我面临着问题。

请查看以下屏幕截图。 text get cut extra space.

假设我的第一个消息长度很大，那么我的第二个消息高度变得相同。

在第二个屏幕截图中，它将显示上一条消息的正确视图。因为我关闭了我的键盘和适配器同时刷新第一个可见视图高度自动增加。

public class ChatAdapter extends BaseAdapter {

    LayoutInflater mInflater;
    ChatActivity chatActivity;
    private DatabaseHandler DatabaseHandler;
    private DatabaseHandler dbHelper;
    private List<HBMessage> mList = new ArrayList<HBMessage>();
    private Context mContext;

    public ChatAdapter(ChatActivity chatActivity) {
        this.chatActivity = chatActivity;
        mContext = chatActivity;
        DatabaseHandler = new DatabaseHandler(mContext);
        dbHelper = new DatabaseHandler(mContext);
    }

    @Override
    public int getCount() {

        return mList.size();
    }

    @Override
    public HBMessage getItem(int position) {
        return mList.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

Answer 1

由于视图回收的行为，无论convertView是否为null，都必须设置和取消设置与内容有关的所有内容。您应该首先将与viewHolder绑定无关的代码移动到之后 if-else。另一个选择是开始使用RecyclerView，它实际上像ListView，它具有改进的回收机制（以及更多）。这是guide。

Answer 2

您需要为所有视图执行一些代码，无论它们是新的还是已回收的。仅对新视图执行viewholder init部分。

if (convertView == null) {
    mHolder = new Holder();
    mInflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    convertView = mInflater.inflate(R.layout.single_chat_item, null);

    mHolder.mSimpleRecieveLayout = (RelativeLayout) convertView.findViewById(R.id.recive_layout);

    mHolder.mSimpleSenderLayout = (RelativeLayout) convertView.findViewById(R.id.sender_layout);
    mHolder.mSentImageLayout = (LinearLayout) convertView.findViewById(R.id.sentImageLayout);
    mHolder.mRecieveImageLayout = (RelativeLayout) convertView.findViewById(R.id.recieveImageLayout);

    mHolder.simpleFriendMessage = (TextView) convertView.findViewById(R.id.txtMesssageSender);
    mHolder.simpleFriendMessageTime = (TextView) convertView.findViewById(R.id.txtTimeSender);
    mHolder.mtxtImageRecieveTime = (TextView) convertView.findViewById(R.id.txtImageRecieveTime);

    mHolder.simpleMyMessage = (TextView) convertView.findViewById(R.id.txtMesssageRecieve);
    mHolder.simpleMyMessageTime = (TextView) convertView.findViewById(R.id.txtTimeRecieve);
    mHolder.mtxtImageSentTime = (TextView) convertView.findViewById(R.id.txtImageSentTime);

    mHolder.mMsgStatus = (TextView) convertView.findViewById(R.id.txtStatusSender);
    mHolder.mtxtImageStatus = (TextView) convertView.findViewById(R.id.txtImageSentStatus);

    mHolder.mimgSent = (ImageView) convertView.findViewById(R.id.imgSent);
    mHolder.mimgRecieve = (ImageView) convertView.findViewById(R.id.imgRecieve);
    mHolder.mSentProgress = (ProgressBar) convertView.findViewById(R.id.sentProgress);
    mHolder.mplayordownload = (ImageView) convertView.findViewById(R.id.playordownload);
    mHolder.mplayorupload = (ImageView) convertView.findViewById(R.id.playorupload);
    mHolder.mDownloadProgress = (ProgressBar) convertView.findViewById(R.id.downloadProgress);

    mHolder.rlImageSendLayout = (RelativeLayout) convertView.findViewById(R.id.chat_rlSendImage);
    mHolder.rlImageReceiveLayout = (RelativeLayout) convertView.findViewById(R.id.chat_rlReceiveImage);
    convertView.setTag(mHolder);
} else {
    mHolder = (Holder) convertView.getTag();
} 
    // This is now executed for all your views.
    int tempWidth = (int) (BaseApplication.SCREEN_WIDTH * 0.28);
    int tempHeight = (int) (BaseApplication.SCREEN_WIDTH * 0.26);

    int imageSize = (int) (tempHeight * 0.84);

    LinearLayout.LayoutParams param1 = (LayoutParams) mHolder.rlImageSendLayout.getLayoutParams();
    param1.width = tempWidth;
    param1.height = tempHeight;
    mHolder.rlImageSendLayout.setLayoutParams(param1);

    RelativeLayout.LayoutParams param2 = (android.widget.RelativeLayout.LayoutParams) mHolder.rlImageReceiveLayout
            .getLayoutParams();
    param2.width = tempWidth;
    param2.height = tempHeight;
    mHolder.rlImageReceiveLayout.setLayoutParams(param2);

    RelativeLayout.LayoutParams param3 = (android.widget.RelativeLayout.LayoutParams) mHolder.mimgSent.getLayoutParams();
    param3.width = imageSize;
    param3.height = imageSize;
    mHolder.mimgSent.setLayoutParams(param3);

    RelativeLayout.LayoutParams param4 = (android.widget.RelativeLayout.LayoutParams) mHolder.mimgRecieve.getLayoutParams();
    param4.width = imageSize;
    param4.height = imageSize;
    mHolder.mimgRecieve.setLayoutParams(param4);

此外，您应该考虑阅读有关在适配器中使用不同视图类型的更多信息（在您的情况下为myLayout和otherLayout）。起点是this。

Answer 3

Finally I have solved this issue by applying stupid thing.Why i am facing issue,that i really don't know and Why its get solved after applying patch that i really don't know.

**My Solution:**

    setMyLayout()
{
    mHolder.mSentMessageLayout
                        .setBackgroundResource(R.drawable.chat_sender);
}    
    setOtherLayout()
{
    mHolder.mRecieveMessageLayout
                        .setBackgroundResource(R.drawable.chat_receiver);
}
