            android:text="Button"
            android:textColor="@color/white" />

    </LinearLayout>
</android.support.v4.widget.NestedScrollView>

myActivity.java

public class MyActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_my);
    }
}

defaultConfig {
    vectorDrawables.useSupportLibrary = true
}

我也尝试了一些事情

static
{
    AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
}

.

public class MyActivity extends AppCompatActivity {

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

Answer 1

不能对drawableLeft,drawableLight使用矢量绘图。对不起。

也试试

        app:drawableEnd="@drawable/ic_warning_white_24px"
        app:drawableRight="@drawable/ic_warning_white_24px"

而不是

        android:drawableEnd="@drawable/ic_warning_white_24px"
        android:drawableRight="@drawable/ic_warning_white_24px"
