使用Glide时发生错误

Question

The app crashes when I try to load an image with Glide .

I have the following code:

.java:

ImageButton home_ib1;

Glide.with(Home.this)
            .load(R.drawable.moviep_24_hours_to_live)
            .override(98, 155)
            .centerCrop()
            .placeholder(R.drawable.moviep_24_hours_to_live)
            .into(home_ib1);

.xml:

<ScrollView
   <RelativeLayout


<ImageButton
            android:id="@+id/home_ib1"
            android:layout_width="98dp"
            android:layout_height="155dp"
            android:layout_marginStart="16dp"
            android:layout_marginTop="155dp"
            android:background="@android:color/transparent"
            android:scaleType="fitCenter"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent" />

And when I try to run app, i got crash..(LogCat: You must pass in a non null View) (The image's resolution that i have to load is 175x276 PNG)

Answer 1

ImageButton home_ib1;

Looks Like home_ib1 is null

Just add

home_ib1 = findViewById(R.id.home_ib1);
