尝试上传项目bintray并获得错误:

Could not determine java version from '9.0.1'.

我读到它的等级错误,它修复了上层版本,我尝试更改gradle版本4.2.1,但得到另一个错误:

Gradle sync失败:没有这样的属性:FOR_RUNTIME for class:org.gradle.api.attributes.Usage有关详细信息,请参阅IDE日志(帮助|显示日志)(571ms)

Gradle属性:

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-4.2.1-all.zip

建立gradle项目

buildscript {
    ext.kotlin_version = '1.1.51'

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0-beta7'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.novoda:bintray-release:0.5.0'

        // 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
}

如何选中所有复选框 recyclerView?

我尝试这样做:

在适配器中:

   public void selectAll(){
        Log.e("onClickSelectAll","yes");
        isSelectedAll=true;
        notifyDataSetChanged();
    }


@Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        PersonDTO item = dataSet.get(position);
        holder.tvName.setText(item.getName());
        if (!isSelectedAll) holder.cbSelect.setSelected(false);
        else holder.cbSelect.setSelected(true);}

在layout Activity我有一个button用onClickListener:

 private void onClickSelectAll(View view) {

        getSelectPersonsAdapter().selectAll();
    }
