The second canvas that image change will happen is this file:

          android:textAppearance="?android:attr/textAppearanceLarge"
          android:textColor="#000000" />

</RelativeLayout>

Java file:

package com.example.flip3d;

import android.app.Activity;
import android.content.Intent;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;
import android.widget.Toast;


public class Cards extends Activity {

  ImageView img1;
  ImageView img2;
  ImageView image;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.cards);

    img1 =(ImageView) findViewById(R.id.img1);
    img2 =(ImageView) findViewById(R.id.img2);
    image =(ImageView) findViewById(R.id.ImageView01);

    img1.setOnClickListener(new View.OnClickListener() {

      public void onClick(View arg0) {

        image.setImageResource(R.drawable.myfirstimage);
        Intent startyou = new Intent("com.example.flip3d.FLIP3D");
        startActivity(startyou);
      }
    });

    img2.setOnClickListener(new View.OnClickListener() {

      public void onClick(View view) {
        image.setImageResource(R.drawable.may2ndimage);

        Toast.makeText(Cards.this, "Card Selected", Toast.LENGTH_SHORT).show();

        Intent startyou = new Intent("com.example.flip3d.FLIP3D");
        startActivity(startyou);
      }
    });

  }

}

My logcat message.

When I run this code on my phone. An error occurred and when I check the logcat it says: that I’m having error with setImageResource();.

What should I do? I’m a beginner in Android programming.

Thanks in advance.

I’m trying to change the source of my ImageButton, but for some reason I keep getting this error message: Cannot resolve method ‘setImageResource’ (android.graphics.drawable.Drawable).

Here’s the code im trying to use:

<ImageButton
        android:layout_width="32dp"
        android:layout_height="32dp"
        android:id="@+id/cuenta_1"
        android:text="cuenta1"
        android:background="@mipmap/ic_fondo"
        android:layout_toLeftOf="@id/agregarCuenta"/>

And in the mainActivity:

Drawable logo = new BitmapDrawable(bitmap);
                        findViewById(R.id.cuenta_2).setImageResource(logo);

Any idea on how I can fix this?

I can see 2 errors

Change

findViewById(R.id.cuenta_2).setImageResource(logo);

to

// Create and cast an object of type ImageButton, with the proper id
ImageButton imb = (ImageButton) findViewById(R.id.cuenta_1); // you were trying to find cuenta_2, which is not in the layout
imb.setImageResource(R.drawables.some_image); // setImageResource takes an int, not a drawable.

Всем привет,столкнулся с такой проблемкой,не могу понять почему setImageResource,крашит приложение делаю так 

ImageView simpleImageView = (ImageView) findViewById(R.id.ColMemberID);
simpleImageView.setImageResource(R.mipmap.ic_launcher);

А в консоле вот так 

W/art: Before Android 4.1, method android.graphics.PorterDuffColorFilter android.support.graphics.drawable.VectorDrawableCompat.updateTintFilter(android.graphics.PorterDuffColorFilter, android.content.res.ColorStateList, android.graphics.PorterDuff$Mode) would have incorrectly overridden the package-private method in android.graphics.drawable.Drawable

Issue

I am trying to create a recycleView with image and toolbar. this is my adapter

public class ImageAdabter extends RecyclerView.Adapter<ImageViewHolder> {

private Context mContext;
private List<Integer> listImages;

public ImageAdabter(Context mContext) {
    this.mContext = mContext;
    this.listImages=getImages();
}

private List<Integer> getImages() {
    List<Integer> results = new ArrayList<>();
    results.add(R.drawable.ballon);
    results.add(R.drawable.owl);
    results.add(R.drawable.fish);
    return results;
}

@NonNull
@Override
public ImageViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
    View view = LayoutInflater.from(mContext).inflate(R.layout.item_images,parent,false);
    return new ImageViewHolder(view);
}

@Override
public void onBindViewHolder(@NonNull ImageViewHolder holder, int position){holder.imageView.setImageResource(listImages.get(position));
}

@Override
public int getItemCount() {
    return listImages.size();
}

and i create a ImageViewHolder class . this is may code

public class ImageViewHolder extends RecyclerView.ViewHolder {

public ImageView imageView;
public ImageViewHolder(@NonNull View itemView) {
    super(itemView);
    itemView= itemView.findViewById(R.id.image_outline);

}

My main class code is

 initTollbar();
    initView();
}

private void initView() {
    recyclerView = findViewById(R.id.recycle_view_images);
    recyclerView.setHasFixedSize(true);
    recyclerView.setLayoutManager(new LinearLayoutManager(this));
    adabter = new ImageAdabter(this);
    recyclerView.setAdapter(adabter);
}

@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
private void initTollbar() {
    Toolbar toolbar = findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    int toolbar_item_color= ResourcesCompat.getColor(getResources(),R.color.blue,null);
    toolbar.setTitleTextColor(toolbar_item_color);
    toolbar.setSubtitleTextColor(toolbar_item_color);
    getSupportActionBar().setTitle("Mes Images");
    getSupportActionBar().setDisplayShowHomeEnabled(true);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setHomeAsUpIndicator(R.drawable.close);
}

@Override
public boolean onOptionsItemSelected(@NonNull MenuItem item) {
    int id = item.getItemId();
    if(id == android.R.id.home){
        finish();
    }
    return super.onOptionsItemSelected(item);
}

when i run my code i got this error

java.lang.NullPointerException: Attempt to invoke virtual method ‘void android.widget.ImageView.setImageResource(int)’ on a null object reference
.adabters.ImageAdabter.onBindViewHolder(ImageAdabter.java:44)
.adabters.ImageAdabter.onBindViewHolder(ImageAdabter.java:17)

thanks

Solution

Use below code

public class ImageViewHolder extends RecyclerView.ViewHolder {

public ImageView imageView;
public ImageViewHolder(@NonNull View itemView) {
    super(itemView);
    imageView = itemView.findViewById(R.id.image_outline);

}
