[Android] 標準アイコンをGridViewで表示

アンドロイドには標準アイコンがあります。アイコン一覧から探せばわざわざアイコンを作ったりしなくてもいいのと、ユーザーからみてもアイコンにAndroidで共通の意味があれば便利です。
　

Android Studio
2021.2.1

Android標準アイコン

　
標準アイコンを使うメリットは、Androidアプリとして標準的なアイコンを提示することにより、ユーザーが暗黙的に意味を素早く理解できることです。
　
またアイコンリストは結構たくさんあるのでGirdViewで表示できるようにしてみました。

標準アイコンの呼び出し

　
画像を用意しませんが、それぞれ特別な呼び出しをします。
javaコードで記述する場合： android.R.drawable.XXX

image.setImageResource(android.R.drawable.ic_input_add);

1	image.setImageResource(android.R.drawable.ic_input_add);

　
xmlレイアウトに記述する場合：

android:src="@android:drawable/alert_dark_frame"

1	android:src="@android:drawable/alert_dark_frame"

　
まとめるとこうなります。
MainActivity.java

import android.app.Activity;
import android.os.Bundle;
import android.widget.ImageView;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        // コードで指定する場合
        ImageView image = findViewById(R.id.icon_1);
        image.setImageResource(android.R.drawable.ic_input_add);
    }
}

import android.app.Activity;

import android.os.Bundle;

import android.widget.ImageView;

public class MainActivity extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

// コードで指定する場合

ImageView image = findViewById(R.id.icon_1);

image.setImageResource(android.R.drawable.ic_input_add);

}

　
レイアウトです
activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:gravity="center"
    tools:context=".MainActivity">

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="10dp"
        android:src="@android:drawable/alert_dark_frame" />

    <ImageView android:id="@+id/icon_1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="10dp" />

</LinearLayout>

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:orientation="vertical"

android:gravity="center"

tools:context=".MainActivity">

<ImageView

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_margin="10dp"

<ImageView android:id="@+id/icon_1"

android:layout_width="wrap_content"

android:layout_margin="10dp" />

</LinearLayout>

　

　
このようになりました。
　

GridView で一覧表示

　
R.Drawableにあるアイコンをリストアップしたアプリを作ってみましょう。
アイコンなのでGridViewがいいでしょう。またアイコンをタップすると名前が表示されるように設計してみます。
　
アイコンの数が多いので、クラスに入れてみました。わかりやすくするために最初の24個のみを記述してみます。
