You trying to set String as a background of your Imageview. You need to load Image from URL. Read this tutorial for fetching Image from URL Or check this answer.

First you have to download Android query jar from here.

Android query is easily downloaded or load image from URL based on AJAX call.
Add jar to project libs folder and add jar to build path.
Activity code

public class MainActivity extends Activity {

Button bt;
EditText et;
ImageView iv;

private AQuery androidQuery;

@Override
 public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

bt = (Button) findViewById(R.id.bt);
et = (EditText) findViewById(R.id.et);
iv = (ImageView) findViewById(R.id.imageView1);
androidQuery = new AQuery(this);

bt.setOnClickListener(new OnClickListener() {
    
    @Override
    public void onClick(View arg0) {
        if(et.getText().toString().trim().length()>0){
        // this code load image form url
         androidQuery.image(et.getText().toString(), true, true); 
                                /*or*/
         // this code download image
         androidQuery.ajax(et.getText().toString(), Bitmap.class, 0, new AjaxCallback<Bitmap>() {
                @Override
                public void callback(String url, Bitmap object, AjaxStatus status) {
                    super.callback(url, object, status);
                    if(object!=null){
                        iv.setImageBitmap(object);
                    }else{
                        // write message if give path image not found
                    }
                }
            });
        }
    }
});
}



    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
     getMenuInflater().inflate(R.menu.activity_main, menu);
      return true;
    }

showing image use after input text URL and press button
