I am new to Android developing. I managed to do a task to change an image for clicking two different buttons.
My MainActivity.java
:
package com.example.sandorhorvath.imageviewchange;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;
public class MainActivity extends AppCompatActivity {
public void lightBox(View view) {
ImageView image = (ImageView) findViewById(R.id.imageView);
image.setImageResource(R.drawable.kawa2);
}
public void lightBox1(View view) {
ImageView image = (ImageView) findViewById(R.id.imageView);
image.setImageResource(R.drawable.kawa1);
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
I want to keep the code really simple and make the same with one button I tried with toggle but I can identify the onClick with lightBox
but where should I identify the lightBox2
? I can turn on the function but I don't find the off function value.
Try this logic for toggling image with only one button ...write this in click func
boolean check = false;
public void lightBox(View view) {
if(check) {
image
.setImageResource(R.drawable.kawa1 );
check = false;}
else {
image
.setImageResource(R.drawable.kawa2 );
check = true;}
}
Working like a charm a little modification added to the code the image had to be defined.
boolean check = false;
public void lightBox(View view) {
ImageView image = (ImageView) findViewById(R.id.imageView);
if(check) {
image.setImageResource(R.drawable.kawa1);
check = false;
} else {
image.setImageResource(R.drawable.kawa2);
check = true;
}
}
Thank you for your help! The logic is perfect!
You can use android.support.design.widget.CheckableImageButton
from the support design library like this:
<android.support.design.widget.CheckableImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textOn="@null"
android:textOff="@null"
android:background="@null"
android:src="@drawable/your_image"/>
