列表视图OnitemClick动画

Question

我做了项目点击动画的列表视图，我使用数组适配器的数据输入和数组适配器我打电话动画类的项目点击保持点击变量clickedposition -1那里我打电话动画....所有细节都在代码.....
`

public class TaskListAdapter extends ArrayAdapter<FTask> { 

    protected FTask[] values= null; 
    protected Context context = null; 
    private int clickedPosition = -1; 

    public TaskListAdapter(Context context,FTask[] values) { 
     this(context, R.layout.task_row, values); 
    } 
    public TaskListAdapter(Context context, int taskRow, FTask[] values) { 
     super(context, taskRow, values); 
     this.values = values; 
     this.context = context; 

    } 
    public void toggle(int position) { 
     //If its already opened. Close it. Else open it. 
     if(clickedPosition == position){ 
      clickedPosition = -1; 
     }else{ 
      clickedPosition = position; 
     } 
     notifyDataSetChanged(); 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     View row = convertView; 
     if (convertView == null) { 
      row = View.inflate(context, R.layout.task_row, null); 
      LinearLayout single_message_holder = (LinearLayout) row 
        .findViewById(R.id.single_task_holder); 
      single_message_holder.setBackgroundColor(Color.WHITE); 
     } 

     final FTask tsk = values[position]; 
     TextView service_description = (TextView) row.findViewById(R.id.task_description); 
     service_description.setText(tsk.getBody()); 


     TextView service_detail_description = (TextView) row.findViewById(R.id.task_detail_description); 
     service_detail_description.setText(tsk.getBody()); 
     LinearLayout ani=(LinearLayout)row.findViewById(R.id.ani); 


     if (clickedPosition == position) { 

      Log.d("****Position*****",String.valueOf(position)); 
      //service_detail_description.setAnimation(AnimationUtils.loadAnimation(context, 
       //  R.anim.push_up_in)); 
      ani.startAnimation(new VisibleAni(1.0f, 1.0f, 0.0f, 1.0f, 800, ani, true,true)); 
      ani.setVisibility(View.VISIBLE); 
      service_description.setVisibility(View.GONE); 
      Log.d("SENDING TASK STATUS", "AGAINNNNN"); 
      sendTaskStatus(tsk); 

     } else { 
      //ani.startAnimation(new VisibleAni(1.0f, 1.0f, 0.0f, 1.0f, 800, ani, true,false)); 
      ani.setVisibility(View.GONE); 
      service_description.setVisibility(View.VISIBLE); 

     } 

     ImageView icon = (ImageView) row.findViewById(R.id.taskicon); 
     if (tsk.isDone()==1) { 
      icon.setImageResource(R.drawable.done); 
      service_description.setPaintFlags(service_description.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG); 
     } else { 
      icon.setImageResource(R.drawable.undone); 
      service_description.setPaintFlags(service_description.getPaintFlags() & ~Paint.STRIKE_THRU_TEXT_FLAG); 
     } 

     icon.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 

       if(tsk.isDone()==0){ 
        tsk.setDone(1); 
        notifyDataSetChanged(); 
       } 
       else{ 
        tsk.setDone(0); 
        notifyDataSetChanged(); 
       } 
      } 
     }); 
     return row; 
    } 
    private void sendTaskStatus(FTask tsk){ 
     //TODO pathch, 
     Log.e("TaskListAdapter", "Set status"); 
     if (LoginManager.getSessionId() == null ||LoginManager.getSessionId().equals("DUMMY") || LoginManager.getSessionId().equals("")){ 
      Log.e("INVALID USER_ID or SESSION_ID", "Not connectind to network"); 
      return; 
     } 
     NetworkDataFetcher fetcher = new NetworkDataFetcher(NetworkDataFetcher.LINK_DATA_ACCESS); 

     try { 
      String response = fetcher.execute(new String[] { MessageManager.MSG_JSON_ID_TYPE, MessageManager.MSG_JSON_ID_SESSIONID, MessageManager.MSG_JSON_ID_MID}, 
        new String[] {"message_status", LoginManager.getSessionId(), tsk.getTskid() }).get(); 

      if(response == null){ 
       Log.e("TaskListAdapter", "response null"); 
       return; 
      } 
      Log.w("TasksListAdapter", "Response = "+response); 
      return; 

     } catch (InterruptedException e) { 
      Log.d("InterrupptedException", "InterrupptedException"); 
      return; 
     } catch (ExecutionException e) { 
      Log.d("ExecutionException", "ExecutionException"); 
      return; 
     } 
    } 
} 

And the Animation Class

import android.view.View; 
import android.view.animation.ScaleAnimation; 
import android.view.animation.Transformation; 
import android.widget.LinearLayout.LayoutParams; 

public class VisibleAni extends ScaleAnimation { 
    private View mView; 

    private LayoutParams mLayoutParams; 

    private boolean mclick; 

    private int mMarginBottomFromY, mMarginBottomToY; 

    private boolean mVanishAfter = false; 

    public VisibleAni(float fromX, float toX, float fromY, float toY, int duration, View view, 
      boolean vanishAfter,boolean click) { 
     super(fromX, toX, fromY, toY); 
     setDuration(duration); 
     mView = view; 
     mclick = click; 
     mVanishAfter = vanishAfter; 
     mLayoutParams = (LayoutParams) view.getLayoutParams(); 
     int height = mView.getHeight(); 
     mMarginBottomFromY = (int) (height * fromY) + mLayoutParams.bottomMargin - height; 
     mMarginBottomToY = (int) (0 - ((height * toY) + mLayoutParams.bottomMargin)) - height; 
     if (!mclick) { 
      mView.setVisibility(View.GONE); 
     } 

    } 

    @Override 
    protected void applyTransformation(float interpolatedTime, Transformation t) { 
     super.applyTransformation(interpolatedTime, t); 
     if (interpolatedTime < 1.0f) { 
      int newMarginBottom = mMarginBottomFromY + (int) ((mMarginBottomToY - mMarginBottomFromY) * interpolatedTime); 
      mLayoutParams.setMargins(mLayoutParams.leftMargin, mLayoutParams.topMargin, 
       mLayoutParams.rightMargin, newMarginBottom); 
      mView.getParent().requestLayout(); 
     } else if (mVanishAfter) { 
      mView.setVisibility(View.VISIBLE); 
     } 

    } 

}  

And the XML file related to this is ..........

<?xml version="1.0" encoding="utf-8"?>

    </LinearLayout>

` 在第一次点击它工作正常，但在第二次我点击它来了同一项目的不规则..........

Answer 1

而是动画视图（LinearLayout中你的情况）你为什么不通过OnItemClickListener设置为您的ListView动画意见

这将做如下

ListView lv = (ListView)findViewById(R.id.listView); 
lv.setOnItemClickListener(new OnItemClickListener() { 

     @Override 
     public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, 
       long arg3) { 
        final View v = arg1; 
        LinearLayout ani = (LinearLayout)v.findViewById(R.id.ani); 
        ani.startAnimation(new VisibleAni(1.0f, 1.0f, 0.0f, 1.0f, 800, ani, true,true)); 
        ani.setVisibility(View.VISIBLE); 
        } 
} 

这应该工作你的情况
