Java 如何在Android中读取TypedArray数据？

我是Android新手，仍然在学习一些教程。一个图坦卡门是关于TypedArray的，用于存储图像信息

MainActivity.java

package com.example.materialme;

import androidx.appcompat.app.AppCompatActivity;
import android.content.res.TypedArray;
import android.os.Bundle;
import android.util.Log;
import java.util.ArrayList;
import java.util.Arrays;

public class MainActivity extends AppCompatActivity {

    private static final String TAG = MainActivity.class.getSimpleName();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        TypedArray sportsImageResources = getResources().obtainTypedArray(R.array.sports_images);
        Log.d(TAG, "sportImageResources: " + sportsImageResources);
        sportsImageResources.recycle();

    }

}

strings.xml

<resources>
    <array name="sports_images">
        <item>@drawable/img_baseball</item>
        <item>@drawable/img_badminton</item>
        <item>@drawable/img_basketball</item>
        <item>@drawable/img_bowling</item>
        <item>@drawable/img_cycling</item>
        <item>@drawable/img_golf</item>
        <item>@drawable/img_running</item>
        <item>@drawable/img_soccer</item>
        <item>@drawable/img_swimming</item>
        <item>@drawable/img_tabletennis</item>
        <item>@drawable/img_tennis</item>
    </array>
</resources>

@可牵引/模拟棒球
@可牵引/img_羽毛球
@可牵引/模拟篮球
@可拉制/模拟保龄球
@可牵引式/img_自行车
@可牵引/img_高尔夫
@可牵引/img_运行
@可牵引/模拟足球
@可牵引/模拟游泳
@可牵引/img_乒乓球
@可牵引/模拟网球

当我在logcat中看到时，TypedArray SportImageResources的值是

[3, 179, 6, 2131165272, 0, 0, 3, 178, 6, 2131165271, 0, 0, 3, 180, 6, 2131165273, 0, 0, 3, 181, 6, 2131165274, 0, 0, 3, 182, 6, 2131165275, 0, 0, 3, 183, 6, 2131165276, 0, 0, 3, 184, 6, 2131165277, 0, 0, 3, 185, 6, 2131165278, 0, 0, 3, 186, 6, 2131165279, 0, 0, 3, 187, 6, 2131165280, 0, 0, 3, 188, 6, 2131165281, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 17, 512, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 16, 250, 1, 0, 1073742848, 0, 16, 400, 1, 0, 1073742848, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 0, 0, -1, 0, 0, 0, 1, 2131558747, 6, 2131558747, 1073742848, 0, 1, 2131558746, 6, 2131558746, 1073742848, 0, 28, -1, 1, 17170443, 1073742848, 0, 3, 193, 6, 2131165294, 1073742848, 0, 3, 27, 6, 0, 1073742848, 0, 18, -1, 6, 0, 1073742848, 0, 18, 0, 6, 0, 1073742848, 0, 18, 0, 6, 0, 1073742848, 0, 0, 0, -1, 0, 1073742848，0，0，0，-1，0，1073742848，0，0，-1，0，1073742848，0，0，0，0，1073742848，0，0，0，0，-1，0，0，0，0，0，-1，0，0，0，18，0，6，0，1073742848，0]

如何读取这些数据？

这个例子可能会对您有所帮助

TypedArray sportsimgs=getResources（）.obtainTypedArray（R.array.random_imgs）

//通过索引获取资源ID
sportsimgs.getResourceId（i，-1）

//或者将ImageView的资源设置为id
mImgView1.setImageResource（sportsimgs.getResourceId（i，-1））

//回收阵列
sportsimgs.recycle（）；

我知道getResourceId（）。我只是想知道为什么TypedArray数组只为少数图像保存这么多值。
