【问题描述】:
我尝试将 GridLayout 用作
GridLayout maingrid=(GridLayout)findViewById(R.id.mainGridView);
但它使我的应用程序崩溃。 针对这个问题上网冲浪给出了我应该使用的解决方案
android.support.v7.widget.GridLayout;
而不是android.widget.GridLayout;,但在使用它时我收到错误无法解决v7。
搜索了这个问题并获得了许多更新 build.gradle 文件的解决方案,但它也因构建而失败。
build.gradle 文件初始:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.4.2'
implementation 'com.android.support:cardview-v7:21.+'
implementation 'com.android.support:recyclerview-v7:21.+'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
更新后:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.4.2'
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:26.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
implementation 'com.android.support:design:26.1.1'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
android {
compileSdkVersion 26
buildToolsVersion "26.0.2"
defaultConfig {
minSdkVersion 16
targetSdkVersion 26
}
}
请帮我解决这个问题
【问题讨论】:
-
可能有些java文件包含android.support.v7.widget.GridLayout;顶部的 import 语句尝试手动删除它们
