 對於這次的界面設計，希望有兩個輸入框，一個是打開本地的視頻，一個是打開網絡直播流。那麽假如這個界面命名為OpenUrl，則有：

AndroidManifest.xml：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.xplay">
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.INTERNET"/>
    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/Theme.Xplay">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name=".OpenUrl"/>
    </application>

</manifest>
所以cpp/native-lib.cpp中就可以將之前寫的固定的死的路徑注釋了：

#include <jni.h>
 #include <string>
 #include <android/native_window_jni.h>
 
 #include "XLog.h"
 #include "IPlayerPorxy.h"
 extern "C"
 JNIEXPORT
 jint JNI_OnLoad(JavaVM *vm,void *res)
 {
     IPlayerPorxy::Get()->Init(vm);
 
     /*IPlayerPorxy::Get()->Open("/sdcard/v1080.mp4");
     IPlayerPorxy::Get()->Start();
 
     
     IPlayerPorxy::Get()->Open("/sdcard/1080.mp4");
     IPlayerPorxy::Get()->Start();*/
 
     return JNI_VERSION_1_4;
 }
 
 extern "C"
 JNIEXPORT void JNICALL
 Java_com_example_xplay_XPlay_InitView(JNIEnv *env, jobject instance, jobject surface) {
 
     // TODO
     ANativeWindow *win = ANativeWindow_fromSurface(env,surface);
     IPlayerPorxy::Get()->InitView(win);
 }
 
 extern "C"
 JNIEXPORT jstring JNICALL
 Java_com_example_xplay_MainActivity_stringFromJNI(JNIEnv *env, jobject thiz) {
     // TODO: implement stringFromJNI()
 }

然後MainActivity.java中就可以實現打開這個新界面的事件：

package com.example.xplay;
 
 import androidx.appcompat.app.AppCompatActivity;
 
 import android.content.Intent;
 import android.os.Bundle;
 import android.util.Log;
 import android.view.View;
 import android.widget.Button;
 import android.widget.TextView;
 
 public class MainActivity extends AppCompatActivity {
 
     // Used to load the 'native-lib' library on application startup.
     static {
         System.loadLibrary("native-lib");
     }
     private Button bt;
     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);
         bt = findViewById( R.id.open_button );
         bt.setOnClickListener( new View.OnClickListener() {
             @Override
             public void onClick(View view) {
                 Log.e("XPlay","open button click!");
                 //打开选择路径窗口
                 Intent intent = new Intent();
                 intent.setClass( MainActivity.this ,OpenUrl.class);
                 startActivity( intent );
 
 
             }
         } );
     }
 
     /**
      * A native method that is implemented by the 'native-lib' native library,
      * which is packaged with this application.
      */
     public native String stringFromJNI();
 }

然後在activity_main.xml中實現按鈕的佈局：

<?xml version="1.0" encoding="utf-8"?>
 <androidx.constraintlayout.widget.ConstraintLayout 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:layout_height="match_parent"
     tools:context=".MainActivity">
     <com.example.xplay.XPlay
         android:layout_width="match_parent"
         android:layout_height="match_parent" />
     <FrameLayout
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         android:fitsSystemWindows="true">
 
         <LinearLayout
             android:id="@+id/fullscreen_content_controls"
 
             android:layout_width="match_parent"
             android:layout_height="wrap_content"
             android:layout_gravity="bottom|center_horizontal"
 
             android:orientation="horizontal"
             tools:ignore="UselessParent">
 
             <Button
                 android:id="@+id/open_button"
                 android:layout_width="0dp"
                 android:layout_height="wrap_content"
                 android:layout_weight="1"
                 android:text="Open"
                 />
             <SeekBar
                 android:id="@+id/aplayseek"
                 android:layout_width="match_parent"
                 android:layout_height="match_parent" />
 
         </LinearLayout>
 
 
     </FrameLayout>
 
 </androidx.constraintlayout.widget.ConstraintLayout>

然後是OpenUrl具體邏輯OpenUrl.java:

package com.example.xplay;
 
 import android.content.pm.ActivityInfo;
 import android.os.Bundle;
 import android.view.Window;
 import android.view.WindowManager;
 import android.widget.TextView;
 
 import androidx.appcompat.app.AppCompatActivity;
 
 /**
  * Created by Administrator on 2018-03-11.
  */
 
 public class OpenUrl extends AppCompatActivity {
     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate( savedInstanceState );
         setContentView( R.layout.openurl );
     }
 
 }

接下來是openurl的具體佈局openurl.xml:

<?xml version="1.0" encoding="utf-8"?>
 <FrameLayout 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:layout_height="match_parent"
     android:background="#0099cc"
     >
 
 
     <LinearLayout
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
         android:fitsSystemWindows="true"
         android:orientation="vertical">
 
 
         <LinearLayout
             android:layout_width="match_parent"
             android:layout_height="wrap_content"
             android:orientation="horizontal">
 
             <EditText
                 android:id="@+id/fileurl"
                 android:layout_width="wrap_content"
                 android:layout_height="wrap_content"
                 android:ems="10"
                 android:inputType="textPersonName"
                 android:text="/sdcard/1080.mp4" />
 
             <Button
                 android:id="@+id/playvideo"
                 android:layout_width="wrap_content"
                 android:layout_height="wrap_content"
                 android:text="播放" />
 
         </LinearLayout>
 
         <LinearLayout
             android:layout_width="match_parent"
             android:layout_height="wrap_content"
             android:orientation="horizontal">
 
             <EditText
                 android:id="@+id/rtmpurl"
                 android:layout_width="wrap_content"
                 android:layout_height="wrap_content"
                 android:ems="10"
                 android:inputType="textPersonName"
                 android:text="rtmp://live.hkstv.hk.lxdns.com/live/hks" />
 
             <Button
                 android:id="@+id/playrtmp"
                 android:layout_width="wrap_content"
                 android:layout_height="wrap_content"
                 android:text="香港卫视直播" />
         </LinearLayout>
     </LinearLayout>
 </FrameLayout>

最後大致的界面
