我试图在列表视图滚动时隐藏工具栏,以便只有选项卡仍然可见,但由于某种原因我不能。
代码:
private void setupPages() {
toolbar = (Toolbar) findViewById(R.id.toolBar);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
if (toolbar != null) {
toolbar.setElevation(0);
}
}
viewPager = (ViewPager) findViewById(R.id.pager);
intent = getIntent();
servitoros_id = intent.getStringExtra(AppConstant.WAITER_INTENT_ID);
magazi_id = intent.getStringExtra(AppConstant.COMPANY_INTENT_ID);
title = intent.getStringExtra(AppConstant.TABLE_INTENT_ID);
if (toolbar != null) {
toolbar.setTitle(getString(R.string.table_id) + title);
}
mAdapter = new ProductsTabPagerAdapter(getSupportFragmentManager(), ProductsViewOrder.this, ProductsViewOrder.this);
viewPager.setAdapter(mAdapter);
tabs = (TabLayout) findViewById(R.id.tabs);
tabs.setupWithViewPager(viewPager);
tabs.setSelectedTabIndicatorHeight(6);
tabs.setSelectedTabIndicatorColor(getResources().getColor(R.color.white));
if (toolbar !=null){
setSupportActionBar(toolbar);
}
coffeesList = new ArrayList<>();
snacksList = new ArrayList<>();
sweetsList = new ArrayList<>();
if (toolbar != null) {
toolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
int id = item.getItemId();
switch (id) {
case R.id.search: {
showSearchResults();
break;
}
case R.id.cart: {
showCart();
break;
}
}
return true;
}
});
}
}

我的 Gradle 依赖项:
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile files('libs/circularimageview.jar')
compile 'com.android.support:appcompat-v7:23.1.0'
compile 'com.android.support:support-v4:23.1.0'
compile 'com.quinny898.library.persistentsearch:library:1.0.0-SNAPSHOT'
compile 'com.android.support:design:23.1.0'
}
