我正在尝试新的底部应用栏。在设计指南中,它被告知“在底部的应用程序栏和FAB上方插入小吃店或吐司”,但我不确定该怎么做。谁能帮我。以下是我正在使用的代码:
MainActivity
public SearchSourceBuilder createQueryForCount(QueryBuilder queryBuilder, int start, boolean fetchSource, String field){
logger.info("Creating aggregation count ");
QueryBuilder finalQuery = QueryBuilders.boolQuery().must(queryBuilder);
AggregationBuilder aggregationCount = AggregationBuilders.terms("agg").field(USER_ID)
.subAggregation(AggregationBuilders.topHits("top").explain(false).from(start))
.subAggregation(AggregationBuilders.count("count").field(field));
return new SearchSourceBuilder()
.query(finalQuery)
.fetchSource(fetchSource)
.from(start)
.aggregation(aggregationCount);
}
activity_main.xml
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = findViewById(R.id.fab);
fab.setOnClickListener(view ->
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show());
}

问题在于,每当我单击android {
compileSdkVersion 28
defaultConfig {
applicationId "..."
minSdkVersion 22
targetSdkVersion 28
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 = '1.8'
targetCompatibility = '1.8'
}
buildToolsVersion = '28.0.2'
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'androidx.appcompat:appcompat:1.0.0'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation 'com.google.android.material:material:1.0.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test:runner:1.1.0-alpha4'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0-alpha4'
}
按钮时,小吃栏就会出现在底部应用程序栏的上方,并且还会将fab推到上方。下面是问题的图像。

content_main
布局中添加一个布局ID,以便您可以通过findViewById
在活动代码中获取对该ID的引用这应该使您的快餐栏出现在BottomAppBar上方。

这是一个已修复的issue。我认为有一个新的API setAnchorView
,我们将继续进行下一个更新;有关详细信息,请访问:https://github.com/material-components/material-components-android/commit/868e80ed6ff183cceeb9c33523bf47f72772c52a

请使用最新的材料库:
编辑build.gradle(模块:应用程序)并将材料:1.0.0更新为1.1.0-alpha04或最新版本:
implementation 'com.google.android.material:material:1.1.0-alpha04'

请使用setAnchorView()方法:-
Snackbar.make(CoordinatorLayoutView, "your text", Snackbar.LENGTH_SHORT)
.setAnchorView(yourfabView.getVisibility() == View.VISIBLE ? YourFabView : BottomAppBarView).show();
