je minLines, maxLines, singleLine="false", inputType="textMultiLine" mais toujours montrer comme ceci:

classe ici mon CustomTextView j'ai cacher une partie de mon code cette le code affiche également le texte sur une seule ligne.

public class CustomTextView extends AppCompatTextView { 

    //Shadow Variable 
    public static int shadow_length = 30; 

    public int x_direction = 1; 
    public int y_direction = 1; 
    boolean shadow_Enable = false; 
    int color = Color.BLACK; 
    float[] hsv = new float[]{0, 0, 0}; 
    int getcol; 
    Paint paint; 
    Paint paint1; 
    Paint paint2; 

    public CustomTextView(Context context, AttributeSet attributeSet) { 
     super(context, attributeSet,android.R.attr.textViewStyle); 
     paint = new Paint(Paint.ANTI_ALIAS_FLAG); 
     paint1 = new Paint(Paint.ANTI_ALIAS_FLAG); 
     paint2 = new Paint(Paint.ANTI_ALIAS_FLAG); 
     textPaint = new TextPaint(Paint.ANTI_ALIAS_FLAG); 
     textPaint.setTextSize(getTextSize()); 
    } 

    @Override 
    protected void onDraw(Canvas canvas) { 
      getPaint().setMaskFilter(null); 
     TextPaint textPaint = getPaint(); 
     float x_position = (getWidth() - getPaint().measureText(getText().toString()))/2f; 
     float y_position = (int) ((getHeight()/2) - ((textPaint.descent() + textPaint.ascent())/2)); 

     getPaint().setColor(shadowColor); 

     //Center point for transformation 
     PointF center_Point = new PointF(getWidth()/2f, getHeight()/2f); 
     Camera camera = new Camera(); 

       canvas.drawText(getText().toString(), x_position, y_position, getPaint()); 
       } 
} 

Answer 1

i supprimer tout x_position et y_position,

@Override 
    protected void onDraw(Canvas canvas) { 

    //......... 
    StaticLayout mTextLayout = new StaticLayout(getText().toString(), getPaint(), canvas.getWidth(), Layout.Alignment.ALIGN_NORMAL, 1.0f, 0.0f, true); 
        canvas.save(); 
    float textHeight = getTextHeight(getText().toString(), textPaint); 
    int numberOfTextLines = mTextLayout.getLineCount(); 
    float textYCoordinate = mTextBounds.exactCenterY() - ((numberOfTextLines * textHeight)/2); 
    // text will be drawn from left 
    float textXCoordinate = mTextBounds.left; 
    canvas.translate(0, 0); 
    // draws static layout on canvas 
    mTextLayout.draw(canvas); 
    canvas.restore(); 
    //..... 
} 

Answer 2

Utilisez

android:maxLength="10"

Comme l'exigence de longueur

le long des lignes max
