Marquee ne fonctionne pas avec la mise à jour de la barre de recherche. (Android)

Question

Je fais un lecteur de musique et ai mis en place un chapiteau dans la chanson et le nom de l'artiste. Mais dès que la barre de recherche est mise à jour, la vue du texte revient à la position d'origine. Donc, de cette façon, une sorte de va-et-vient du texte est vu. Merci de m'aider.

Voici le code XML

Here is the design

Voici le code Java

public class MainFullPlayer extends AppCompatActivity { 

private static RelativeLayout fullPlayer; 
private static ImageView fullPlayer_play , fullPlayer_next , 
fullPlayer_prev,fullPlayer_album; 
private static TextView fullPlayer_song , fullPlayer_artist , 
fullPlayer_currentTime , fullPlayer_maxTime; 
private static SeekBar seekBar; 
private Songs song; 
private static Handler progressHandler; 
private static Runnable progressRunnable; 


@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main_full_player); 
    fullPlayer = (RelativeLayout)findViewById(R.id.mainFullPlayerContainer); 
    fullPlayer_play = (ImageView)findViewById(R.id.imageView_full_player_play); 
    fullPlayer_next = (ImageView)findViewById(R.id.imageView_full_player_next); 
    fullPlayer_prev = (ImageView)findViewById(R.id.imageView_full_player_prev); 
    fullPlayer_album = (ImageView)findViewById(R.id.imageView_full_player_album_art); 
    fullPlayer_song = (TextView)findViewById(R.id.textView_full_player_song); 
    fullPlayer_artist = (TextView)findViewById(R.id.textView_full_player_artist); 
    fullPlayer_currentTime = (TextView)findViewById(R.id.textView_current_time); 
    fullPlayer_maxTime = (TextView)findViewById(R.id.textView_total_length); 

    fullPlayer_maxTime.setText(MusicPlayback.getTime(MusicPlayback.mediaPlayer.getDuration())); 

    seekBar = (SeekBar)findViewById(R.id.seekBar); 

    song = MusicPlayback.allTracks.get(MusicPlayback.songPosition); 
    fullPlayer_song.setSelected(true); 
    fullPlayer_artist.setSelected(true); 
    fullPlayer_song.setText(song.getSongName()); 
    fullPlayer_artist.setText(song.getArtist()); 


    if(MusicPlayback.getPlayingStatus()){ 
     fullPlayer_play.setImageResource(R.drawable.icon_pause_small); 
    } 
    else 
    { 
     fullPlayer_play.setImageResource(R.drawable.icon_play_small); 
    } 
    if(song.getAlbumArt()!= null){ 

     fullPlayer_album.setImageURI(Uri.parse(song.getAlbumArt())); 
     fullPlayer.setBackground(FragmentAllTracks.d); 
    } 
    else{ 
     fullPlayer_album.setImageResource(R.drawable.default_album_art); 
     fullPlayer.setBackgroundColor(Color.argb(255, 48, 48, 48)); 

    } 
seekBar.setMax(MusicPlayback.mediaPlayer.getDuration()); 


    progressHandler = new Handler(); 

    progressRunnable = new Runnable() { 
     @Override 
     public void run() { 
      seekBar.setProgress(MusicPlayback.mediaPlayer.getCurrentPosition()); 
      fullPlayer_currentTime.setText(MusicPlayback.getTime(MusicPlayback.mediaPlayer.getCurrentPosition())); 


      progressHandler.postDelayed(progressRunnable,100); 
     } 
    }; 
    progressHandler.postDelayed(progressRunnable,100); 
} 


@Override 
public void onBackPressed() { 
    super.onBackPressed(); 
    this.overridePendingTransition(R.anim.left_exit_translate,R.anim.right_exit_translate); 

} 




} 

Voici le résultat

Unable to get Marquee

Answer 1

Je pense que c'est en raison de la concentration. S'il vous plaît définir votre textview comme celui-ci

<TextView 
    android:id="@+id/textView_full_player_song" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:layout_alignEnd="@+id/imageView_full_player_album_art" 
    android:layout_alignStart="@+id/imageView_full_player_album_art" 
    android:layout_below="@+id/imageView_full_player_album_art" 
    android:layout_marginTop="12dp" 
    android:singleLine="true" 
    android:ellipsize="marquee" 
    android:marqueeRepeatLimit ="marquee_forever" 
    android:focusable="true" 
    android:focusableInTouchMode="true" 
    android:scrollHorizontally="true" 
    android:text="Song Name" 
    android:textAlignment="center" 
    android:textColor="@color/defaultTextColor" 
    android:textSize="18sp" /> 

ajouter ce votre TextView,

android:focusable="true" 
android:focusableInTouchMode="true" 

Answer 2

Essayez d'utiliser cette MarqueeTextView classe, il règle automatiquement la taille fixe pour TextView il ne sera pas re-mesure (la raison Cause animation de défilement de redémarrage):

public class MarqueeTextView extends AppCompatTextView implements View.OnLayoutChangeListener { 
    public MarqueeTextView(Context context) { 
     this(context, null); 
    } 

    public MarqueeTextView(Context context, AttributeSet attrs) { 
     this(context, attrs, 0); 
    } 

    public MarqueeTextView(Context context, AttributeSet attrs, int defStyleAttr) { 
     super(context, attrs, defStyleAttr); 
     setSingleLine(); 
     setEllipsize(TextUtils.TruncateAt.MARQUEE); 
     setMarqueeRepeatLimit(-1); 
     setSelected(true); 

     addOnLayoutChangeListener(this); 
    } 

    @Override 
    public boolean isFocused() { 
     return true; 
    } 

    @Override 
    public void onWindowFocusChanged(boolean hasWindowFocus) { 
     if (hasWindowFocus) super.onWindowFocusChanged(hasWindowFocus); 
    } 

    @Override 
    protected void onFocusChanged(boolean focused, int direction, Rect previouslyFocusedRect) { 
     if (focused) super.onFocusChanged(focused, direction, previouslyFocusedRect); 
    } 

    @Override 
    public void onLayoutChange(View v, int left, int top, int right, int bottom, 
           int oldLeft, int oldTop, int oldRight, int oldBottom) { 
     ViewGroup.LayoutParams layoutParams = getLayoutParams(); 
     layoutParams.height = bottom - top; 
     layoutParams.width = right - left; 
     removeOnLayoutChangeListener(this); 
     setLayoutParams(layoutParams); 
    } 
}
