如何从点击RecyclerView开始活动

大家好我试图开始活动，当我点击RecyclerView，它开始时，我将代码添加到自定义适配器，但是当我写它在活动它只是给我在日志中的位置.. 所以任何帮助如何从点击RecyclerView开始活动

这里是代码的OnClick的活动，而这正是我试图做

@Override 
    public void onItemClick(int position, View v) { 
     Log.e("TAG", "You clicked number " + mAdapter.getItemId(position) + ", which is at cell position " + position); 
//  this.startActivity(new Intent(FrameListActivity.this , FinalActivity.class)); 
//  Bitmap frameSelected = results.get(position).getImage(); 
//  Log.e("frameSelected" , frameSelected+""); 
//  createImageFromBitmap(frameSelected , "frameImage"); 
     positionId = "" + position; 
     Context context = v.getContext(); 
     Intent intent = new Intent(context.getApplicationContext() , FinalActivity.class); 
     intent.putExtra("resultpos", "" + positionId); 
     context.getApplicationContext().startActivity(intent); 
     finish(); 
    }

这里是活动

这里是适配器....

public class PhotoRecyclerViewAdapter extends RecyclerView.Adapter<PhotoRecyclerViewAdapter.DataObjectHolder> { 

    private static String LOG_TAG = "MyRecyclerViewAdapter"; 
    private List<PhotoClass> mDataset; 
    private static MyClickListener myClickListener;

    public interface MyClickListener {

这里是类...

    public int getId() { 
     return id; 
    } 

    public int getImage() { 
     return image; 
    } 

}

FinalActivity的OnCreate

@Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     Log.i(TAG, "Activity Created"); 
     setContentView(R.layout.activity_final); 

     mGlobal = (Global) getApplicationContext(); 

     imageViewThumbnail = (ImageView) findViewById(R.id.selectedimage); 
     saveIcon = (ImageView) findViewById(R.id.imageSave); 
     filterIcon = (ImageView) findViewById(R.id.editImage); 
     mImageViewFrame = (ImageView) findViewById(R.id.frameimage); 
//  mInterstitialAd = new InterstitialAd(this); 
//  mInterstitialAd.setAdUnitId(getApplicationContext().getString(R.string.admob_intersitials)); 
//  mAdRequest= new AdRequest.Builder().build(); 
//  mInterstitialAd.loadAd(mAdRequest); 
     imageViewThumbnail.setOnTouchListener(new MultiTouchListener()); 
     mDialog = Utils.SetProgressBar(mDialog, FinalActivity.this); 
     mDialog.dismiss(); 

     loadImage(imageViewThumbnail, mGlobal.getPath()); 
     String result = getIntent().getStringExtra("resultpos"); 
     pos = Integer.parseInt(result); 
     Log.w("Position===", "" + pos); 
     String imagevalue = frames[pos]; 
     Log.w("imagename=====++++", "" + imagevalue); 
     int resID = getResources().getIdentifier(imagevalue, "drawable", getPackageName()); 
     mImageViewFrame.setImageResource(resID); 
     saveIcon.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
//    if (mInterstitialAd.isLoaded()) { 
//     mInterstitialAd.show(); 
//    } 
       RelativeLayout view = (RelativeLayout) findViewById(R.id.layout); 
       view.setDrawingCacheEnabled(true); 
       view.buildDrawingCache(); 
       Bitmap bm = view.getDrawingCache(); 
       SaveImage(bm); 
      } 
     }); 
     filterIcon.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       RelativeLayout view = (RelativeLayout) findViewById(R.id.layout); 
       view.setDrawingCacheEnabled(true); 
       view.buildDrawingCache(); 
       Bitmap bm = view.getDrawingCache(); 
       EditImage(bm); 

      } 
     });}

的LoadImage功能：

private void loadImage(ImageView iv, final String path) { 
     if(!isAirplaneModeOn(this.getApplicationContext())) { 
      Picasso.with(FinalActivity.this) 
        .load(Uri.fromFile(new File(path))) 
        .fit() 
        .centerInside() 
        .into(iv, new Callback() { 
         @Override 
         public void onSuccess() { 
          Log.i(TAG, "Picasso Success Loading Thumbnail - " + path); 
         } 

         @Override 
         public void onError() { 
          Log.i(TAG, "Picasso Error Loading Thumbnail Small - " + path); 
         } 
        }); 
     } 
     else{ 
      //do something else? 
     } 

     File image = new File(path); 
     BitmapFactory.Options bmOptions = new BitmapFactory.Options(); 
     Bitmap bitmap = BitmapFactory.decodeFile(image.getAbsolutePath(), bmOptions); 
     engrave(bitmap); 

//  bitmap = Bitmap.createScaledBitmap(bitmap,parent.getWidth(),parent.getHeight(),true); 
    } 



    @SuppressWarnings("deprecation") 
    @TargetApi(Build.VERSION_CODES.JELLY_BEAN_MR1) 
    public static boolean isAirplaneModeOn(Context context) { 
     if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN_MR1) { 
      return Settings.System.getInt(context.getContentResolver(), 
        Settings.System.AIRPLANE_MODE_ON, 0) != 0; 
     } else { 
      return Settings.Global.getInt(context.getContentResolver(), 
        Settings.Global.AIRPLANE_MODE_ON, 0) != 0; 
     } 
    } 
}

发布类的完整代码.. – rafsanahmad007

试试这个：在

您onResume():您已经安装setOnItemClickListener到PhotoRecyclerViewAdapter

@Override 
protected void onResume() { 
    super.onResume(); 
    ((PhotoRecyclerViewAdapter) mAdapter).setOnItemClickListener(new PhotoRecyclerViewAdapter 
      .MyClickListener() { 
     @Override 
     public void onItemClick(int position, View v) { 
      Log.i(LOG_TAG, " Clicked on Item " + position); 
      Intent intent = new Intent(FrameListActivity.this , FinalActivity.class); 
      intent.putExtra("resultpos", "" + position); 
      startActivity(intent); 
     } 
    }); 
}

它的工作...谢谢sooo多:) –

我现在有另一个问题，当它开始活动需要很长时间像3秒，请你审查代码和谢谢:) –

sry为迟到的回应....把一个日志在'onResume（）'看看它是否立即调用...我认为你的''FinalActivity'类可能会做沉重的操作，这就是为什么它需要时间来加载新的活动.... – rafsanahmad007

使用th是：

@Override 
    public void onItemClick(int position, View v) { 
     Log.e("TAG", "You clicked number " + mAdapter.getItemId(position) + ", which is at cell position " + position); 
//  this.startActivity(new Intent(FrameListActivity.this , FinalActivity.class)); 
//  Bitmap frameSelected = results.get(position).getImage(); 
//  Log.e("frameSelected" , frameSelected+""); 
//  createImageFromBitmap(frameSelected , "frameImage"); 
     positionId = "" + position; 
     Context context = FrameListActivity.this; 
     Intent intent = new Intent(context , FinalActivity.class); 
     intent.putExtra("resultpos", "" + positionId); 
     context.startActivity(intent); 
     finish(); 
    }

希望这会有所帮助。

不，它不工作:(它只是回归的位置 –

检查我的更新的答案，context.startActivity（intent），您是否在活动中添加了自定义适配器？ – tahsinRupam

是的，我没有向我展示带有数据的适配器，如果我没有添加，更新不起作用乙醚 –
