        android:src="@drawable/quo100px"
        android:visibility="gone" />

tks advance for your help

Answer 1

For that you have to check if you are taking string for compression than use .equalsIgnoreCase("") function otherwise use == to compare .

Answer 2

You are checking for a String in which case the .equals("your_constraint") is used.

So, change this:

if (cu == "1") {
    cu = "oui";
} else {
    ImageView image_A_wrong = (ImageView) findViewById(R.id.imageView1);
    image_A_wrong.setVisibility(View.GONE);
}

to this:

if (cu.equals("1")) {
    cu = "oui";
} else {
    ImageView image_A_wrong = (ImageView) findViewById(R.id.imageView1);
    image_A_wrong.setVisibility(View.GONE);
}

Answer 3

Use cu.equals("1") rather than cu == "1" and you'll be fine
