Question

我试图在单击滑动选项卡布局中的选项卡时获得涟漪效果，但它无法正常工作。

custom_tab_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/tabContainer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:padding="15dp"
>

<ImageView
    android:id="@+id/tabImage"
    android:layout_width="match_parent"
    android:background="@drawable/tab_bg"
    android:layout_height="wrap_content"
    android:layout_gravity="center" />

<TextView
    android:id="@+id/tabText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="bottom|center" />

下面是可绘制的xml文件以获得涟漪效应

V22 / tab_bg.xml

<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="?android:attr/colorControlHighlight">
<item
    android:id="@+id/mask"
    android:drawable="@color/white"></item>
</ripple>

下面是MainActivity，我已经为滑动标签实现了背景和指示器的颜色。

MainActivty.java

  mTabs.setCustomTabView(R.layout.custom_tab_layout, R.id.tabText);
    mTabs.setDistributeEvenly(true);

    mTabs.setBackgroundColor(getResources().getColor(R.color.colorPrimary));
    mTabs.setSelectedIndicatorColors(getResources().getColor(R.color.accentColor));
    mTabs.setViewPager(mPager);

感谢任何帮助.. !!

Answer 1

在SlidingTabLayout.java中 - ＆gt; createDefaultTabView（）你会发现

TypedValue outValue = new TypedValue();

只需将此背景添加为 selectableItemBackground

getContext().getTheme().resolveAttribute(android.R.attr.selectableItemBackground, outValue, true);

供参考，请参阅此SlidingTabLayout (Gist)。

修改：

很好，现在我得到了你的问题.. 将 custom_tab_layout.xml 背景设置为 selectableItemBackground

android:background="?attr/selectableItemBackground"

Answer 2

我找到了一个用于在滑动标签中获得涟漪效果的库。让我在这里发布两个文件。

在Android Studio中，在build.gradle中添加依赖项（编译＆＃39; it.neokree：MaterialTabs：0.11＆＃39;）

请参阅此https://github.com/neokree/MaterialTabs

activity_tab_library.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout        xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="match_parent"

tools:context="com.example.ramz.material_udemy_slidnerd.TabLibrary">

<include
android:id="@+id/app_bar"
layout="@layout/app_bar" />

<!-- for Text Tabs -->
<it.neokree.materialtabs.MaterialTabHost
android:id="@+id/materialTabHost"
android:layout_width="match_parent"
android:layout_height="48dp"

app:accentColor="#FF9800"
app:primaryColor="#673AB7"
app:textColor="#FFFFFF" />

<android.support.v4.view.ViewPager
android:id="@+id/viewPager"
android:layout_width="match_parent"

android:layout_height="0dp"
android:layout_weight="1"/>

</LinearLayout>

3.TabLibrary.java

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentStatePagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;

import it.neokree.materialtabs.MaterialTab;
import it.neokree.materialtabs.MaterialTabHost;
import it.neokree.materialtabs.MaterialTabListener;


public class TabLibrary extends AppCompatActivity implements MaterialTabListener {

private MaterialTabHost tabHost;
private ViewPager viewPager;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tab_library);
Toolbar toolbar = (Toolbar) findViewById(R.id.app_bar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);

tabHost = (MaterialTabHost) findViewById(R.id.materialTabHost);
viewPager = (ViewPager) findViewById(R.id.viewPager);

ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(adapter);
//  viewPager.setAdapter(new ViewPagerAdapter(getSupportFragmentManager()));
viewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
    @Override
    public void onPageSelected(int posiiton) {
        tabHost.setSelectedNavigationItem(posiiton);
    }
});
for (int i = 0; i < adapter.getCount(); i++) {
    tabHost.addTab(tabHost.newTab().setText(adapter.getPageTitle(i)).setTabListener(this));
}


}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_activity_using_library, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();

//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {


    return true;
}

return super.onOptionsItemSelected(item);
}



@Override
public void onTabSelected(MaterialTab materialTab) {
viewPager.setCurrentItem(materialTab.getPosition());

}

@Override
public void onTabReselected(MaterialTab tab) {

}

@Override
public void onTabUnselected(MaterialTab tab) {

}

public class ViewPagerAdapter extends FragmentStatePagerAdapter {

public ViewPagerAdapter(FragmentManager fm) {
    super(fm);
}

@Override
public Fragment getItem(int num) {
    return MainActivity.Myfragment.getInstance(num);
}

@Override
public int getCount() {
    return 3;
}

@Override
public CharSequence getPageTitle(int position) {
    return getResources().getStringArray(R.array.tabs)[position];

}

}

}

这就是全部，我们可以在这里添加任意数量的标签。谢谢

尝试使用Android设计支持中的TabLayout

compile 'com.android.support:design:23.1.0'

布局：

xmlns:app="http://schemas.android.com/apk/res-auto"
...
<android.support.design.widget.TabLayout
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:tabBackground="?attr/selectableItemBackground"/>
