Why isn't my vector drawable scaling as expected?

Question

I am attempting to use vector drawables in my Android app. From http://developer.android.com/training/material/drawables.html (emphasis mine):

In And

Answer 1

First : import svg to drawble : ((https://www.learn2crack.com/2016/02/android-studio-svg.html))

1-Right click on the drawable folder select New -> Vector Asset

2- The Vector Asset Studio provides you option to select the inbuilt Material icons or your own local svg file. You can override the default size if needed.

Second :if you want support from android API 7+ , you have to use Android Support Library acording ((https://stackoverflow.com/a/44713221/1140304))

1- add

vectorDrawables.useSupportLibrary = true

to your build.gradle file.

2-Use namespace in your layout that has imageView :

xmlns:app="http://schemas.android.com/apk/res-auto"

Third : set imageView with android:scaleType="fitXY" and use app:srcCompat

Fourth :if you want set svg in java code you have to add below line on oncreate methoed

 @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
