I am creating app in which there is screen with searchBar by this lib. My activity layout looks like this:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

<android.support.constraint.ConstraintLayout
        android:id="@+id/wrapper"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:animateLayoutChanges="true">

    <TextView
            android:id="@+id/title"
            android:textColor="@color/colorPrimary"
            android:text="@string/mainScreenTitle"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:textAlignment="center"
            app:layout_constraintLeft_toLeftOf="parent"
            app:layout_constraintRight_toRightOf="parent"
            android:paddingTop="100dp"/>

    <com.arlib.floatingsearchview.FloatingSearchView
            android:id="@+id/searchView"
            android:layout_width="0dp"
            android:layout_height="50dp"
            android:layout_marginTop="100dp"
            android:animateLayoutChanges="true"
            app:layout_constraintLeft_toLeftOf="parent"
            app:layout_constraintRight_toRightOf="parent"
            app:layout_constraintTop_toBottomOf="@+id/title"/>

</android.support.constraint.ConstraintLayout>

</RelativeLayout>

There i have to move FloatingSearchingView to top of screen and change height to for example 500dp - like this:

app:layout_constraintTop_toTopOf="parent"
android:layout_height="500dp"

And later …

我正在尝试使用基于BetterVideoPlayer库的视频播放器创建活动。当播放器必须缓冲大约 100Mb 的视频时，总是在此日志之后：

W/art: Suspending all threads took: 6.342ms

当库尝试继续缓冲时（例如暂停 20% 后），我得到以下信息：

W/MediaHTTPConnection: readAt 28213248 / 32768 => java.net.ProtocolException: unexpected end of stream

并且播放器由于没有来源而抛出错误我尝试使用另一个库但我遇到了相同的情况。

有我的活动：

package pl.---.---.ui.videoPlayer;

import android.net.Uri;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;

import com.halilibo.bettervideoplayer.BetterVideoPlayer;

import pl.---.---.R;

import butterknife.BindView;
import butterknife.ButterKnife;

public class VideoPlayerActivity extends AppCompatActivity {

    @BindView(R.id.player)
    BetterVideoPlayer player;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_video_player);
        ButterKnife.bind(this);

        Bundle extras = getIntent().getExtras();
        String link = extras.getString("link");
        String title = extras.getString("title");

        player.setSource(Uri.parse(link));
        player.setTitle(title);
    }
}

我能做些什么来解决这个问题？
