I tried to use GridLayout as
GridLayout maingrid=(GridLayout)findViewById(R.id.mainGridView); But it was crashing my application. Surfing internet for the problem gave solution that i should use
android.support.v7.widget.GridLayout; instead of android.widget.GridLayout; but while using this i am getting error could not resolve v7.
Searched for this problem and got many solution to update build.gradle file but it also fails by build.
build.gradle file Initially:
// 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 } After updating:
// 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 } } please help me in resolving this issue
