使数组在整个android生命周期中都可访问

public class MyApplication extends Application {
    public static int[] myArray;

    @Override
    public void onCreate() {
        super.onCreate();
        // 初始化数组
        myArray = new int[]{1, 2, 3, 4, 5};
    }
}

int[] myArray = new int[]{1, 2, 3, 4, 5};
Intent intent = new Intent(this, ReceiverActivity.class);
intent.putExtra("myArray", myArray);
startActivity(intent);

int[] receivedArray = getIntent().getIntArrayExtra("myArray");

int[] myArray = new int[]{1, 2, 3, 4, 5};
SharedPreferences sharedPreferences = getSharedPreferences("MyPrefs", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putInt("arraySize", myArray.length);
for (int i = 0; i < myArray.length; i++) {
    editor.putInt("arrayValue_" + i, myArray[i]);
}
editor.apply();

SharedPreferences sharedPreferences = getSharedPreferences("MyPrefs", Context.MODE_PRIVATE);
int arraySize = sharedPreferences.getInt("arraySize", 0);
int[] retrievedArray = new int[arraySize];
for (int i = 0; i < arraySize; i++) {
    retrievedArray[i] = sharedPreferences.getInt("arrayValue_" + i, 0);
}
