在扩展ImageView的类中设置OnClick

import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.widget.ImageView;
import android.widget.Toast;

public class CustomImageView extends ImageView {
    private Context mContext;

    public CustomImageView(Context context) {
        super(context);
        mContext = context;
    }

    public CustomImageView(Context context, AttributeSet attrs) {
        super(context, attrs);
        mContext = context;
    }

    public CustomImageView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        mContext = context;
    }

    public void setOnClick() {
        this.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                // 在这里实现点击事件的逻辑
                Toast.makeText(mContext, "ImageView被点击了", Toast.LENGTH_SHORT).show();
            }
        });
    }
}

<com.example.CustomImageView
    android:id="@+id/customImageView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/image"
    />

CustomImageView customImageView = findViewById(R.id.customImageView);
customImageView.setOnClick();
