This article shares the specific code for Android to realize the barrage effect for your reference. The specific content is as follows
First of all, let’s analyze it. It is done by three-layer layouts, including the first layer of video layout, the second layer of subtitle layout, and the third layer of input frame layout. If you want these three layouts to be on the same page, you must use relative layout or frame layout.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:andro
xmlns:app="/apk/res-auto"
xmlns:tools="/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:
tools:context="">
<VideoView
android:
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
/>
<
android:
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<LinearLayout
android:
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_alignParentBottom="true"
android:visibility="gone"
android:background="#fff"
android:orientation="horizontal"
>
<EditText
android:
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="match_parent" />
<Button

android:layout_height="match_parent" />
</LinearLayout>
</RelativeLayout>
Create a barrage parser
public class MainActivity extends AppCompatActivity {
private boolean showDanmaku;
private DanmakuView danmakuView;
private DanmakuContext danmakuContext;
//Create a barrage parser private BaseDanmakuParser parser=new BaseDanmakuParser() {
@Override
protected IDanmakus parse() {
return new Danmakus();
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
(savedInstanceState);
setContentView(.activity_main);
//Play video VideoView video_view= (VideoView) findViewById(.video_view);
Uri uri=("://"+getPackageName()+"/"+.minion_08);
video_view.setVideoURI(uri);
video_view.start();
danmakuView= (DanmakuView) findViewById(.danmaku_view);
//The enableDanmakuDrawingCache() method is called to improve the drawing efficiency, that is, the drawing speed // The setCallback() method is called again to set the callback function. (true);
(new () {
@Override
public void prepared() {
showDanmaku=true;
();
}
@Override
public void updateTimer(DanmakuTimer timer) {
}
@Override
public void danmakuShown(BaseDanmaku danmaku) {
}
@Override
public void drawingFinished() {
}
});
danmakuContext=();
//The first parameter is the parser of the barrage //Call the prepare() method of DanmakuView to prepare. After the preparation is completed, the prepared() method in the callback function just set will be automatically called. (parser,danmakuContext);
final LinearLayout operationLayout= (LinearLayout) findViewById(.operation_text);
final Button send= (Button) findViewById();
final EditText edit_text= (EditText) findViewById(.edit_text);
(new () {
@Override
public void onClick(View view) {
if (()==){
();
}else{
();
}
}
});
(new () {
@Override
public void onClick(View view) {
String content=edit_text.getText().toString();
if (!(content)){
addDanmaku(content,true);
edit_text.setText("");
}
}
});
}
@Override
public void onWindowFocusChanged(boolean hasFocus) {
(hasFocus);
if (hasFocus&& .SDK_INT>=19){
View decorView=getWindow().getDecorView();
(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
|View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
|View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
|View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
|View.SYSTEM_UI_FLAG_FULLSCREEN
|View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
);
}
}
private void addDanmaku(String content,boolean withBorder){
BaseDanmaku danmaku=
.createDanmaku(BaseDanmaku.TYPE_SCROLL_RL);
=content;
=5;
=50;
(());
if (withBorder){
(danmaku);
}
}
Finally, the page is displayed horizontally:
<activity android:name=".MainActivity"
Just add this line of code
android:screenOrientation="landscape"
>
<intent-filter>
<action android:name="" />
<category android:name="" />
</intent-filter>
</activity>
