how define if for backgroand of image botton in java

Time:12-19

I want to design a game with Java and I want to do something in the project if the background value of an image button is equal to a certain image, how can I do this?

I have no idea about this problem and I do not know how to define if for photos ...

this is java code:

    package com.example.myapplication;

import androidx.appcompat.app.AppCompatActivity;
import android.annotation.SuppressLint;
import android.os.Bundle;
import android.widget.Button;
import android.widget.ImageButton;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {
    @SuppressLint({"UseCompatLoadingForDrawables", "SetTextI18n"})
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        TextView mnm = findViewById(R.id.textView);
        Button but = findViewById(R.id.button);
        Button butt = findViewById(R.id.buttonn);
        ImageButton but1 = findViewById(R.id.button1);
        ImageButton but2 = findViewById(R.id.button2);
        ImageButton but3 = findViewById(R.id.button3);
        ImageButton but4 = findViewById(R.id.button4);
        ImageButton but5 = findViewById(R.id.button5);
        ImageButton but6 = findViewById(R.id.button6);
        ImageButton but7 = findViewById(R.id.button7);
        ImageButton but8 = findViewById(R.id.button8);
        ImageButton but9 = findViewById(R.id.button9);
        but.setOnClickListener(view -> {
            but1.setOnClickListener(View -> but1.setBackground(getDrawable(R.drawable.ic_baseline_panorama_fish_eye_24)));
            but2.setOnClickListener(View -> but2.setBackground(getDrawable(R.drawable.ic_baseline_panorama_fish_eye_24)));
            but3.setOnClickListener(View -> but3.setBackground(getDrawable(R.drawable.ic_baseline_panorama_fish_eye_24)));
            but4.setOnClickListener(View -> but4.setBackground(getDrawable(R.drawable.ic_baseline_panorama_fish_eye_24)));
            but5.setOnClickListener(View -> but5.setBackground(getDrawable(R.drawable.ic_baseline_panorama_fish_eye_24)));
            but6.setOnClickListener(View -> but6.setBackground(getDrawable(R.drawable.ic_baseline_panorama_fish_eye_24)));
            but7.setOnClickListener(View -> but7.setBackground(getDrawable(R.drawable.ic_baseline_panorama_fish_eye_24)));
            but8.setOnClickListener(View -> but8.setBackground(getDrawable(R.drawable.ic_baseline_panorama_fish_eye_24)));
            but9.setOnClickListener(View -> but9.setBackground(getDrawable(R.drawable.ic_baseline_panorama_fish_eye_24)));
        });
        butt.setOnClickListener(view -> {
            but1.setOnClickListener(View -> but1.setBackground(getDrawable(R.drawable.ic_baseline_clear_24)));
            but2.setOnClickListener(View -> but2.setBackground(getDrawable(R.drawable.ic_baseline_clear_24)));
            but3.setOnClickListener(View -> but3.setBackground(getDrawable(R.drawable.ic_baseline_clear_24)));
            but4.setOnClickListener(View -> but4.setBackground(getDrawable(R.drawable.ic_baseline_clear_24)));
            but5.setOnClickListener(View -> but5.setBackground(getDrawable(R.drawable.ic_baseline_clear_24)));
            but6.setOnClickListener(View -> but6.setBackground(getDrawable(R.drawable.ic_baseline_clear_24)));
            but7.setOnClickListener(View -> but7.setBackground(getDrawable(R.drawable.ic_baseline_clear_24)));
            but8.setOnClickListener(View -> but8.setBackground(getDrawable(R.drawable.ic_baseline_clear_24)));
            but9.setOnClickListener(View -> but9.setBackground(getDrawable(R.drawable.ic_baseline_clear_24)));
        });
        if(but1.getBackground() == getDrawable(R.drawable.ic_baseline_clear_24)){
            mnm.setText("mmd");
        }
    }
}

and this is xml code:

enter image description here

befor your answer, thans a lot

CodePudding user response:

Try to use tag function in view like

but1.setTag("image1")

then check with

boolean sameImage = but1.getTag().equals(but2.getTag());

CodePudding user response:

setting a shadow might work

or the below, but here am using edges with red color

<?xml version="1.0" encoding="UTF-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle"> <corners android:radius="1dp"/> <stroke android:width="6dp" android:color="@color/red"/> </shape>

or check this Android LinearLayout : Add border with shadow around a LinearLayout

Comparing images (KOTLIN)

if (languageFlag.drawable.constantState != getDrawable(R.drawable.ic_french_flag)?.constantState) {
                    languageFlag.setImageResource(R.drawable.ic_french_flag)
    //                Toast.makeText(
    //                    this,
    //                    "Vous devez redémarrer l'application après avoir modifié ce paramètre",
    //                    Toast.LENGTH_LONG
    //                ).show()
                    
                }
