我有一个网页视图，我将在其中输入网址并将该内容加载到该网络视图。

activity_main.xml

我在几个Android设备上测试了这个，比如moto e（4.4.2），戴尔场地7（4.4.2），三星Duos GT-s7392（4.1.2）和Videocon z40pro（4.2.2）上面给出的URL与缅甸字体工作正常。但是当我尝试在Samsung GT-s7582（4.2.2）中加载时，在web视图中缺少myanmar字体。所以，请让我知道如何解决这个问题。

答案 0 :(得分：0)

如果您从资源文件夹中获取数据，我的意思是资产文件夹然后尝试这种方式。

Java代码 

    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    Button buttonPlayVideo = (Button)findViewById(R.id.playvideoplayer);
    Button buttonPlayVideo1 = (Button)findViewById(R.id.button1);
    Button acceess = (Button)findViewById(R.id.button2);

    getWindow().setFormat(PixelFormat.UNKNOWN);

    //Displays a video file.   


   buttonPlayVideo1.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        // VideoView refference see main.xml
        VideoView mVideoView = (VideoView)findViewById(R.id.videoview);

        //String uriPath = "android.resource://com.android.AndroidVideoPlayer/"+R.raw.k;
        String uriPath = "android.resource://com.android.AndroidVideoPlayer/"+R.raw.demo;

        Uri uri = Uri.parse(uriPath);
        mVideoView.setVideoURI(uri);
        mVideoView.requestFocus();
        mVideoView.start();


    }
});

如果您从URL或FTP服务器或HTTP连接获取，请尝试这种方式

Java页面 

    buttonPlayVideo.setOnClickListener(new Button.OnClickListener(){

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
             //VideoView mVideoView = (VideoView)findViewById(R.id.videoview);

             Intent browserIntent = 
                     new Intent(Intent.ACTION_VIEW, Uri.parse("http://192.168.0.8/aeon/"));  // For Video Content
                    // new Intent(Intent.ACTION_VIEW, Uri.parse("ftp://movies:movies@192.168.0.8/Transport_Streams/"));

            startActivity(browserIntent);




        }});

    acceess.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent i = new Intent(AndroidVideoPlayer.this,Videopage.class);
            startActivity(i);

        }
    });
 }

两种方式的XML代码都是按照以下方式给出的

从资源中获取时的XML页面 

<?xml version="1.0" encoding="utf-8"?>

        android:layout_height="wrap_content"
        android:layout_alignBaseline="@+id/playvideoplayer"
        android:layout_alignBottom="@+id/playvideoplayer"
        android:layout_toRightOf="@+id/playvideoplayer"
        android:background="@drawable/button"
        android:text="Acces" />


    <WebView
        android:id="@+id/webView1"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</RelativeLayout>
