因此,出于某种原因,当我放入广告时,它不会自动填充广告:adSize和ads:adUnitId,我无法选择它们,而我的广告显示的文字显示缺少必需的XML属性"adSize".我也不认为我可以在我的布局中填写xmlns:ads,虽然我可能弄错了.为什么是这样？

我的渐变

    // Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.2'
        classpath 'com.google.gms:google-services:3.0.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

第二个build.gradle

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.0"
    defaultConfig {
        applicationId "com.example.matig.adtest"
        minSdkVersion 15
        targetSdkVersion 25 …

我正在尝试创建一个随机生成的字符串.问题是,按照我设置的方式,它继续添加到自身.

我的代码(我从另一个类调用了很多静态变量,所以不要担心那部分)

    class Generate1 extends Thread{
    @Override
    public void run() {
        while(RUNNING == true){
                generate();
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }
    private void generate(){
        for(int i=0;i<length;i++){
            int decider = rando.nextInt(6)+1;

            if(decider == 1){
                sb1.append("A");
            }
            if(decider == 2){
                sb1.append("B");
            }
            if(decider == 3){
                sb1.append("C");
            }
            if(decider == 4){
                sb1.append("D");
            }
            if(decider == 5){
                sb1.append("E");
            }
            if(decider == 6){
                sb1.append("F");
            }
        }
        Log.d("PSS",sb1.toString()); // this here is the stringbuilder being outputted 
    }
}

如果我将长度设置为2,在我的日志中它看起来像:
