GridView is crashing my app - how to fix that?

Question

I have wrote an app but till now without Grid view works very good the problem is that when I have declared the Grid View into the activity main now the app crashed at launch. The same code I have wrote in another project and Grid View works very good.

This is my code.

This is the Image Adapter for Grid View

package com.example.zhuniqia.searchwithus;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;


public class ImageAdapter extends BaseAdapter {
    private Context mContext;
    private int icons[];
    private String textView[];
    private LayoutInflater inflater;

    public ImageAdapter(Context c, int icons[], String textView[] ) {
    this.mContext = c;
    this.icons = icons;
    this.textView = textView;
    }

    public int getCount() {
        return textView.length;
    }

    public Object getItem(int position) {
        return textView[position];
    }

    public long getItemId(int position) {
        return position;
    }

    // create a new ImageView for each item referenced by the Adapter
    public View getView(int position, View convertView, ViewGroup parent) {
       View gridView = convertView;
        if (convertView == null) {
            inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            gridView = inflater.inflate(R.layout.list_grid, null);
            // if it's not recycled, initialize some attributes
        }
        ImageView icon = (ImageView) gridView.findViewById(R.id.icons);
        TextView letter = (TextView) gridView.findViewById(R.id.textView);
        icon.setImageResource(icons[position]);
        letter.setText(textView[position]);
        return gridView;
        }

}

@TheWanderer to hellp me if I have write something wrong so that makes app crashing — TheCoderGuy, Nov 09 '18 at 12:14
It says me it is in the ImageAdapter gridView = inflater.inflate(R.layout.list_grid, null); — TheCoderGuy, Nov 09 '18 at 12:18
@Aaron Caused by: android.view.InflateException: Binary XML file line #7: Error inflating class ImageView This error it is shown for this line gridView = inflater.inflate(R.layout.list_grid, null); — TheCoderGuy, Nov 09 '18 at 12:29

I'm not sure about your drawable in your ImageView, but it sure has problem inflating it. So try using app:srcCompat instead:

<ImageView
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/icons"
    android:layout_width="wrap_content"
    android:layout_marginTop="8dp"
    android:layout_marginLeft="8dp"
    app:srcCompat="@drawable/ic_home_button"
    android:layout_height="wrap_content" />

Or just remove android:src="@drawable/ic_home_button" since you're always going to set image to it in your adapter.

Also please check your ic_home_button drawable files again, make sure they are in the right place. If it's locate only in drawable-v24, then move it out to drawable or somewhere appropriate.

Otherwise, instead of getting LayoutInflater from the system service, try:

inflater = LayoutInflater.from(parent.getContext());
gridView = inflater.inflate(R.layout.list_grid, parent, false);

Which is not working? You've got to be clear with the errors. – Aaron Nov 09 '18 at 12:48
I have tried both of the solutions you have answered but it is making the app crashing again in the same place tells me error. – TheCoderGuy Nov 09 '18 at 12:54
Interesting, how about instead of getting layout inflater from the system, try `LayoutInflater.from(parent.getContext()).inflate(R.layout.list_grid, parent, false)` – Aaron Nov 09 '18 at 13:03
Incompatible Types: Required: android.view.LayoutInflater Found: android.view.View – TheCoderGuy Nov 09 '18 at 13:37
My bad, forgot to break the lines. – Aaron Nov 09 '18 at 13:42
No error but still it is crashing the app in this line. icon.setImageResource(icons[position]); – TheCoderGuy Nov 09 '18 at 13:46
Good, at least it inflates now, what type of error? Maybe work around with setImageDrawable or use AppCompatResources. – Aaron Nov 09 '18 at 13:57

it is a png (v24)

Copy this image in drawable folder not drawable-v24 only
if you have not already done so.
Otherwise it can't be found for other android versions.
