So I’m making a test app more to study even, I’m beginner on android do not know much, I’m trying to make in the application when I click on an image that it enters this method :
p1.setOnClickListener(new ImageView.OnClickListener() {
@SuppressWarnings("ResourceType")
public void onClick(View arg0) {
posicao =1;
Toast.makeText(getContext(), "Imagem 1 selecionada!", Toast.LENGTH_SHORT).show();
}});
I’m wondering why when he enters this method, he does not assign value to the variable position, I have tried other way declared another variable there and made the position receive what was inside but it doesn’t work like this.
These are the images this code above is from the first image, the action when you click on the image and says that it was selected..
The variable position would be the variable that would define the value of if down there, so much so that when I declare for example position = 1 , ie position gets one out of the function it works smoothly, further inside the P1 method which is the left image is as if the position = 1 was not typed there.
at the end of the post has my complete code...
public class Fragment_main extends Fragment {
public Fragment_main() {
}
private int posicao=0;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
final View Acess = inflater.inflate(R.layout.fragment_main, container, false);
ImageView p1 = (ImageView)Acess.findViewById(R.id.p1);
ImageView p2 = (ImageView)Acess.findViewById(R.id.p2);
p1.setOnClickListener(new ImageView.OnClickListener() {
@SuppressWarnings("ResourceType")
public void onClick(View arg0) {
posicao =1;
Toast.makeText(getContext(), "Imagem 1 selecionada!", Toast.LENGTH_SHORT).show();
}});
p2.setOnClickListener(new ImageView.OnClickListener() {
@SuppressWarnings("ResourceType")
public void onClick(View arg0) {
Toast.makeText(getContext(), "Imagem 2 selecionada!", Toast.LENGTH_SHORT).show();
posicao =2;
}});
// position =1;
// pegando o valor que recebeu lá ....
if (posicao==1) {
Button caso1button = (Button) Acess.findViewById(R.id.bts); // botão
//ImageView imagePreview = (ImageView)acessR.findViewById(R.id.viewimg); // idimg
//imagePreview.setImageResource(R.drawable.colorpass); // local da img original
caso1button.setOnClickListener(new Button.OnClickListener() {
@SuppressWarnings("ResourceType")
@Override
public void onClick(View arg0) {
WallpaperManager myWallpaperManager
= WallpaperManager.getInstance(getContext());
try {
myWallpaperManager.setResource(R.drawable.gpx17); // wallpaper
Toast.makeText(getContext(), "Wallpaper aplicado com Sucesso!", Toast.LENGTH_SHORT).show();
} catch (IOException e) {
e.printStackTrace();
}
}
});
posicao = 0;
}else if (posicao==2) {
Button caso2button = (Button) Acess.findViewById(R.id.bts); // botão
//ImageView imagePreview = (ImageView)acessR.findViewById(R.id.viewimg); // idimg
//imagePreview.setImageResource(R.drawable.colorpass); // local da img original
caso2button.setOnClickListener(new Button.OnClickListener() {
@SuppressWarnings("ResourceType")
@Override
public void onClick(View arg0) {
WallpaperManager myWallpaperManager
= WallpaperManager.getInstance(getContext());
try {
myWallpaperManager.setResource(R.drawable.gpx15); // wallpaper
Toast.makeText(getContext(), "Wallpaper aplicado com Sucesso!", Toast.LENGTH_SHORT).show();
} catch (IOException e) {
e.printStackTrace();
}
}
});
posicao = 0;
}
return Acess;
}
}
Oops Brawl, it worked great, I didn’t think I’d have to do just that.
