我试图通过下面的命令改变不包含音频流的视频的速度

String[]{"ffmpeg", "-y", "-i", orginalFile, "-threads", "5", "-preset", "ultrafast", "-strict", "experimental", "-filter_complex", "[0:v]setpts=0.50*PTS[v];[0:a]atempo=2.0[a]", "-map", "[v]", "-map", "[a]", "-b", "2097k", "-ab", "48000", "-ac", "2", "-ar", "22050", "-vcodec", "mpeg4", destinationFile};

命令失败,表明视频没有音频流.那么,我是否需要检查视频中是否存在音频流,或者在这种情况下我能做些什么？

我将服务器迁移HTTP到了HTTPS我已经使用自签名证书发送网络请求HttpUrlConnection并且它工作但是对于图像加载它不起作用,因为我使用Glide进行图像加载.

javax.net.ssl.SSLHandshakeException:java.security.cert.CertPathValidatorException:未找到证书路径的信任锚.从https URL通过滑动库加载图像

Glide.with(mContext).load(currentItem.getImage_path().replace(" ", "%20"))
     .listener(new RequestListener<String, GlideDrawable>() {
        @Override
        public boolean onException(Exception e, String model, Target<GlideDrawable> target, boolean isFirstResource) {
            genericViewHolder.imageView_1.setImageResource(R.drawable.image_thumbnail);
            genericViewHolder.progressBar.setVisibility(View.GONE);
            return false;
        }

        @Override
        public boolean onResourceReady(GlideDrawable resource, String model, Target<GlideDrawable> target, boolean isFromMemoryCache, boolean isFirstResource) {
            genericViewHolder.progressBar.setVisibility(View.GONE);
            return false;
        }
    }).into(genericViewHolder.imageView_1);

我尝试使用此链接并使用GlideModule但它似乎不起作用.请帮忙.

我在xml中给了TextView的电子邮件链接,但是当我点击TextView时它显示不支持的操作错误,如何在textview中将活动链接放在电子邮件中？

这是我的string.xml文件代码:

     <resources>
           <string name="emailLink"><a href="mailto:info@knowledgewoods.in">info@knowledgewoods.in</a></string>
     <resources>

和mylayout.xml

      <TextView 
         android:layout_width="fill_parent"
         android:layout_height="wrap_content"
         android:textSize="15dp"
         android:textColor="@color/text_color"
         android:layout_marginTop="10dp"
         android:id="@+id/text_email"
         android:autoLink="email"
         android:text="@string/emailLink"/>

我在Android 2.2及更高版本中运行我的应用程序.

请帮帮我...谢谢

我正在尝试在整个 RecyclerView 上实现滑动手势来显示/隐藏缩略图。请看下图。

它正在工作，但工作不顺利。有时，如果我们开始滚动 recyclerView，它会突然滚动。

请在下面找到我的代码

....

public class ChatFragment extends Fragment implements View.OnTouchListener {

OnSwipeInteractionListener listener;
private OnListFragmentInteractionListener mListener;
private int min_distance = 100;
private float downX, downY, upX, upY;
private NestedScrollView nestedScrollView;

/**
 * Mandatory empty constructor for the fragment manager to instantiate the
 * fragment (e.g. upon screen orientation changes).
 */
public ChatFragment() {
}

public static ChatFragment newInstance(int columnCount) {
    ChatFragment fragment = new ChatFragment();
    Bundle args = new Bundle();
    fragment.setArguments(args);
    return fragment;
}

@Override
public …

如果ListView适配器中没有数据,我想显示刷新Button和TextView.我还希望能够向将重新加载列表的按钮添加单击侦听器.以下是我定义当前活动的方式:

 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.foods);

    arrList=new ArrayList<FoodsData>();

    listView=(ListView)findViewById(R.id.list_foods);

    this.listView.setEmptyView(findViewById(R.id.emptyView));

    .....
    .....
}

这是我的xml文件:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:orientation="vertical"
    android:layout_height="match_parent">
<LinearLayout 
    android:layout_height="wrap_content"
    android:layout_width="wrap_content"
    android:orientation="vertical"
    android:layout_centerInParent="true"
    android:id="@+id/emptyView">
    <TextView
        android:layout_width="wrap_content"
        android:textColor="@android:color/white"
        android:layout_height="wrap_content"
        android:textSize="20sp"
        android:text="Click Refresh to load data"/>
   <Button 
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/btn_retry"
        android:textColor="@android:color/white"
        android:background="@drawable/orange_button_selecter"
        android:layout_gravity="center"
        android:textSize="25sp"
        android:text="@string/retry"/>
</LinearLayout>
<ListView 
    android:layout_height="wrap_content"
    android:layout_width="wrap_content"
    android:dividerHeight="2dp"
    android:id="@+id/list_foods"/>

我在哪里设置刷新按钮的点击监听器？

我试图通过给其pendingIntent提供唯一的requesCode来在位置监听器中添加多个邻近警报,但我无法获取我设置位置的警报.应用程序也多次崩溃,请帮忙

这是我的代码

        public class LocationTrackerService extends Service implements LocationListener                       {
            private static final long RADIUS = 1000; // in Meters
            private static final long PROX_ALERT_EXPIRATION_TIME = -1;
            Context context;
            String msg;
            LocationManager locationManager;
            public final int MINIMUM_UPDATE_DISTANCE = 100;// in meters
            public final int MINIMUM_UPDATE_INTERVAL = 30 * 1000;// in seconds
            public static String PROX_ALERT_INTENT = "com.ginormous.transportmanagement.ProximityAlert";
            LocationAlertReceiver proximityAlertReceiver;
            private static final NumberFormat nf = new DecimalFormat("##.########");
            IntentFilter filter; 
            ArrayList<LocationModel> locationdata;

            @Override
            public int onStartCommand(Intent intent, int flags, int startId) …
