无法将图片显示（显示）到Android Project中

Question

i've just started android programming and i can't put the image into MainActivity.java. I get an error.

Multiple markers at this line

 -Syntax error, insert "... VariableDeclaratorId" to complete 
 FormalParameterList
- Syntax error, insert "... VariableDeclaratorId" to complete 
 FormalParameterList
- Syntax error on token "setImageResource", Identifier expected after 
 this token 

Java code is (i get an error on 2nd line)

.....
      final ImageView image = (ImageView) findViewById(R.id.ImageView1);
    image.setImageResource(R.drawable.ic_launcher);
    }

Android is

   <ImageView 
    android:id="@+id/ImageView1"
    android:contentDescription="@string/desc"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/ic_launcher"
  />    

Help me please, i really can't understand what is that, i've been stucking on it for 2 weeks!

Answer 1

I guess ic_launcher is not in drawable folder, but in mipmap. So you need to use R.mipmap.ic_launcher in code and @mipmap/ic_launcher in xml

Answer 2

Why have you declared ImageView variable as final ? If you declared a variable as final , it can never be changed after it has been defined . So, try to remove final keyword of image declaration.

You could also remove android:src declaration from your layout, instead of removing final keyword.
