Editext給出IndexOutOfBound異常

我創建了一個自定義的EditText，以便能夠移動和調整EditText的大小。它正在使用我的手機，但是當我開始打字時，卻在其他手機上發生了碰撞。Editext給出IndexOutOfBound異常

當我加入android:inputType="text"到XML代碼它的工作，但應用程序的整個目的丟失以下是完整的堆棧錯誤

這裏是XML代碼

<RelativeLayout 
      android:id="@+id/TextRoot" 
      android:layout_width="match_parent" 
      android:layout_height="match_parent"> 

      <com.oluwayomi.quotage.custom.DragEditText 
       android:id="@+id/etText" 
       style="@style/Widget.AppCompat.Button.Borderless" 
       android:layout_width="wrap_content" 
       android:layout_height="wrap_content" 
       android:layout_centerHorizontal="true" 
       android:layout_gravity="center" 
       android:layout_marginTop="124dp" 
       android:background="@drawable/null_background" 
       android:gravity="center" 
       android:padding="10dp" 
       android:hint="Type text here.\n Double tap to edit \n and long press to resize." 
       android:textSize="22sp" /> 
     </RelativeLayout>

這裏是我自定義的代碼EditText

public DragEditText(Context context) { 
     this(context, null); 

    } 

    public DragEditText(Context context, AttributeSet attrs) { 
     super(context, attrs);

     c = context; 

     RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT); 
     this.setLayoutParams(layoutParams); 
    } 

    public DragEditText(Context context, AttributeSet attrs, int defStyleAttr) { 
     this(context, attrs); 

    } @Override 
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { 
     super.onMeasure(widthMeasureSpec, heightMeasureSpec); 
     int viewWidth = MeasureSpec.getSize(widthMeasureSpec); 
     int viewHeight = MeasureSpec.getSize(heightMeasureSpec); 

     mParentWidth = c.getResources().getDisplayMetrics().widthPixels; 
     mParentHeight = c.getResources().getDisplayMetrics().heightPixels; 
     mParentRect = new RectF(0, 0, viewWidth, viewHeight); 
    }

     } 

     private void drawHandles(Canvas canvas) { 
      //drawHandleShadows(canvas); 
      mPaintFrame.setStyle(Paint.Style.FILL_AND_STROKE);

       canvas.drawRect(mFrameRect.right - mHandleSize, mFrameRect.top + mHandleSize, mFrameRect.right, mFrameRect.bottom - mHandleSize, mPaintFrame); 
      } 

     } 

     private void drawHandleShadows(Canvas canvas) { 
      mPaintFrame.setStyle(Paint.Style.FILL); 
      mPaintFrame.setColor(TRANSLUCENT_BLACK); 
      RectF rect = new RectF(mFrameRect); 
      rect.offset(0, 1); 
      if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {

嘗試刪除提示中的\ n –

嘗試刪除android：gravity =「center」 – Krutik

我已將其移除，但仍然會拋出java.lang.IndexOutOfBoundsException –

Afte r搜索沒有看到有用的解決方案，我終於發現問題

style="@style/Widget.AppCompat.Button.Borderless"

無法應用EditText。

感謝大家。
