在 XML 中使用 GridView，获取 java.lang.UnsupportedOperationException: AdapterView 不支持 addView(View, LayoutParams)

Question

每次我尝试启动我的应用程序时它都会崩溃并在 logcat

中留下这条消息

Caused by: android.view.InflateException: Binary XML file line #15 in com.example.connect3game:layout/activity_main: addView(View, LayoutParams) is not supported in AdapterView

Caused by: java.lang.UnsupportedOperationException: addView(View, LayoutParams) is not supported in AdapterView

这是我的代码：

MainActivity.java

    boolean gameActive = true;

    public void dropIn(View view){

        ImageView counter = (ImageView) view;

        int tappedCounter = Integer.parseInt(counter.getTag().toString());

        if(gameState[tappedCounter] == 2 && gameActive) {

            gameState[tappedCounter] = activePlayer;

            counter.setTranslationY(-1500);


            if (activePlayer == 0) {
                counter.setImageResource(R.drawable.yellow);
                activePlayer = 1;

            } else {

            counter.setImageDrawable(null);

        }

        }

Answer 1

您的 GridView 缺少 numColumns 属性并且其子项必须具有 layout_width="match_parent"。例如：

<GridView
    android:id="@+id/grid"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:horizontalSpacing="6dp"
    android:numColumns="2"
    android:verticalSpacing="6dp" >

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="match_parent"
        android:layout_height="100dp"
        android:onClick="dropIn"
        app:srcCompat="@drawable/grid" />

    <ImageView
        android:id="@+id/imageView2"
        android:layout_width="match_parent"
        android:layout_height="100dp"
        android:onClick="dropIn"
        app:srcCompat="@drawable/grid" />

</GridView>

Answer 2

您的问题是您不能直接在 XML 中将子级添加到 <GridView>（或其他 AdapterView 子类，例如 ListView）。您需要创建一个 ListAdapter 并使用来自 Java/Kotlin 代码的项目创建项目。

但是，如果您尝试在 XML 中创建网格，那可能不是您想要的。您可能正在寻找 GridLayout。
