我有摄像机图像的动态ImageView的，我的问题是我想设置的ImageView我选择刻度标记。请帮我。

  @覆盖保护无效的onCreate（捆绑savedInstanceState）{    super.onCreate（savedInstanceState）;    的setContentView（R.layout.headshotallphoto）;    dbHeadshot =新DataHelperHeadshot（本）;    DisplayMetrics displaymetrics =新DisplayMetrics（）;    。getWindowManager（）getDefaultDisplay（）getMetrics（displaymetrics）。    HT = displaymetrics.heightPixels;    重量= displaymetrics.widthPixels;    GridView控件imagegrid =（GridView控件）findViewById（R.id.PhoneImageGrid）;    imagegrid.setAdapter（新ImageAdapter（getApplicationContext（），BMP））;    imagegrid.setOnItemClickListener（本）;}公共类ImageAdapter延伸BaseAdapter{    私人语境mContext;    私人位图[] mImageArray;    公共ImageAdapter（上下文C，位图[] imgArray）    {          mContext = C;          mImageArray = imgArray;    }    公众诠释getCount将（）    {          返回mImageArray.length;    }    公共对象的getItem（INT位置）    {          返回的位置;    }    众长getItemId（INT位置）    {          返回的位置;    }    公共查看getView（INT位置，查看convertView，父母的ViewGroup）    {        System.gc（）的;        ImageView的I = NULL; // =新ImageView的（mContext.getApplicationContext（））;        如果（convertView == NULL）        {            I =新ImageView的（mContext）;            i.setLayoutParams（新GridView.LayoutParams（92,92））;            i.setScaleType（ImageView.ScaleType.CENTER_CROP）;            i.setPadding（8,8，8,8）;            i.setImageBitmap（mImageArray [位置]）;        }         其他             I =（ImageView的）convertView;         返回我;    }}公共位图德codeFILE（字符串文件路径）{    BitmapFactory.Options O =新BitmapFactory.Options（）;    o.inJustDe codeBounds = TRUE;    BitmapFactory.de codeFILE（文件路径，O）;    //我们希望新的大小缩放到    最终诠释REQUIRED_SIZE = 100;    最终诠释H = 50;    //找到正确的比例值。它应该是2的幂。    INT width_tmp = o.outWidth，height_tmp = o.outHeight;    int标= 1;    而（真）{        如果（width_tmp＆LT; REQUIRED_SIZE＆放大器;＆安培; height_tmp＆LT; H）            打破;        width_tmp / = 2;        height_tmp / = 2;        规模* = 2;    }    //德code。与inSampleSize    BitmapFactory.Options O2 =新BitmapFactory.Options（）;    o2.inSampleSize =规模;    位= BitmapFactory.de codeFILE（文件路径，O2）;    返回位图;}公共无效onItemClick（适配器视图＆LT;＆gt;一种，视图V，INT位置，长的ID）{    ImageView的对勾标记=新ImageView的（本）;    tickmark.setBackgroundResource（R.drawable.imgredselectmark）;} 

解决方案

使用框架布局：

 ＆LT;的FrameLayout        机器人：layout_width =WRAP_CONTENT        机器人：layout_height =WRAP_CONTENT        机器人：方向=垂直        机器人：填充=5dip＆GT;        ＆LT; ImageView的    机器人：ID =@ + ID / image_check            机器人：方向=垂直    机器人：layout_width =WRAP_CONTENT    机器人：layout_height =WRAP_CONTENT            机器人：SRC =@绘制/滴答/＆GT;                ＆LT; ImageView的                机器人：ID =@ + ID / ImageView的                机器人：layout_width =FILL_PARENT                机器人：layout_height =WRAP_CONTENT                机器人：SRC =@绘制/图像＆GT; 

在GridView的

  gridview.setOnItemClickListener（新OnItemClickListener（）{    @覆盖    公共无效onItemClick（适配器视图＆LT;＆GT;母公司，最终意见认为，最终诠释的位置，                长ID）{            view.setOnClickListener（新View.OnClickListener（）{@覆盖公共无效的onClick（视图v）{// TODO自动生成方法存根如果（view.findViewById（R.id.image_check）.getVisibility == ImageView.VISIBLE）   {view.findViewById（R.id.image_check）.setVisibility（ImageView.VISIBLE）   }  其他  {view.findViewById（R.id.image_check）.setVisibility（ImageView.GONE）  }}}}）; 

I have a dynamic imageview of camera picture, my problem is I want to set tick mark on imageview which i select. Please help me.

@Override
protected void onCreate(Bundle savedInstanceState) 
{   
    super.onCreate(savedInstanceState);
    setContentView(R.layout.headshotallphoto);
    dbHeadshot = new DataHelperHeadshot(this);

    DisplayMetrics displaymetrics = new DisplayMetrics();       
    getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);      
    ht = displaymetrics.heightPixels;      
    wt = displaymetrics.widthPixels;        

    GridView imagegrid = (GridView) findViewById(R.id.PhoneImageGrid);
    imagegrid.setAdapter(new ImageAdapter(getApplicationContext(),bmp));
    imagegrid.setOnItemClickListener(this); 
}

public class ImageAdapter extends BaseAdapter
{
    private Context mContext;
    private Bitmap[] mImageArray;

    public ImageAdapter(Context c, Bitmap[] imgArray) 
    {
          mContext = c;
          mImageArray = imgArray;

    }
    public int getCount() 
    {
          return mImageArray.length;

    }
    public Object getItem(int position)
    {
          return position;
    }
    public long getItemId(int position)
    {
          return position;
    }

    public View getView(int position,View convertView,ViewGroup parent)
    {
        System.gc();
        ImageView i = null ;//= new ImageView(mContext.getApplicationContext());

        if (convertView == null) 
        {               
            i = new ImageView(mContext);
            i.setLayoutParams(new GridView.LayoutParams(92,92));
            i.setScaleType(ImageView.ScaleType.CENTER_CROP);
            i.setPadding(8, 8, 8, 8); 
            i.setImageBitmap(mImageArray[position]);              
        }
         else 
             i = (ImageView) convertView;           
         return i;
    }
}

public Bitmap decodeFile(String filePath) 
{
    BitmapFactory.Options o = new BitmapFactory.Options();
    o.inJustDecodeBounds = true;
    BitmapFactory.decodeFile(filePath, o);

    // The new size we want to scale to
    final int REQUIRED_SIZE = 100;
    final int H = 50;

    // Find the correct scale value. It should be the power of 2.
    int width_tmp = o.outWidth, height_tmp = o.outHeight;
    int scale = 1;
    while (true) {
        if (width_tmp < REQUIRED_SIZE && height_tmp < H)
            break;
        width_tmp /= 2;
        height_tmp /= 2;
        scale *= 2;
    }
    // Decode with inSampleSize
    BitmapFactory.Options o2 = new BitmapFactory.Options();
    o2.inSampleSize = scale;        
    bitmap = BitmapFactory.decodeFile(filePath, o2);
    return bitmap;
}

public void onItemClick(AdapterView<?> a, View v, int position, long id) 
{
    ImageView tickmark = new ImageView(this);
    tickmark.setBackgroundResource(R.drawable.imgredselectmark);
}

Use Frame layout:

 <FrameLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:padding="5dip">
        <ImageView
    android:id="@+id/image_check"
            android:orientation="vertical"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
            android:src="@drawable/tick"/>
                <ImageView
                android:id="@+id/imageview"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:src="@drawable/image">

In GridView

gridview.setOnItemClickListener(new OnItemClickListener(){

    @Override
    public void onItemClick(AdapterView<?> parent, final View view, final int position,
                long id) {
            view.setOnClickListener(new View.OnClickListener(){

@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(view.findViewById(R.id.image_check).getVisibility==ImageView.VISIBLE)
   {
view.findViewById(R.id.image_check).setVisibility(ImageView.VISIBLE)
   }
  else
  {
view.findViewById(R.id.image_check).setVisibility(ImageView.GONE)
  }

}
}
});
