我在和api 21 emulator上进行测试，我意识到我的2个gridlayouts没有出现，但在api 30上运行良好。
我试着从 GridLayout 至 android.support.v7.widget.GridLayout ，但我得到一个 Cannot resolve class android.support.v7.widget.GridLayout 错误。
这是我的 activity.xml .

这是我的build.gradle（模块：app）

plugins {
    id 'com.android.application'
}

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.2"

    defaultConfig {
        applicationId "guilherme.battlleship"
        minSdkVersion 21
        targetSdkVersion 30
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

dependencies {

    implementation 'com.google.android.material:material:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.0'

    implementation 'com.android.support:gridlayout-v7:27.1.1'

    androidTestImplementation 'androidx.test.ext:junit:1.1.1'

}

如您所见，我尝试导入gridlayout-v7，但没有成功。它的构建没有任何问题，但是当我启动包含gridlayout视图的活动时，我得到以下错误： Error inflating class android.support.v7.widget.GridLayout 提前谢谢。
编辑：
忘了提一下，但我在每个gridlayout中添加了多个TextView，使用以下循环：

for (int i = 0; i < gameBoard.size(); i++) {
            for (int j = 0; j < gameBoard.get(i).size(); j++) {

                GridLayout.LayoutParams param = new GridLayout.LayoutParams(
                        GridLayout.spec(GridLayout.UNDEFINED, 1f),
                        GridLayout.spec(GridLayout.UNDEFINED, 1f)
                );

                param.width = 0;
                param.height = 0;

                Spot boardSpot = gameBoard.get(i).get(j);

                TextView spot = new TextView(this);

                spot.setTag(i + "," + j);
                spot.setBackground(boardSpot.getShape());
    .
    .
    .
    .
                board.addView(spot, param);
            }
        }
