自訂EditText控制項

大家都知道 系統的EditText長按都是有 複製、粘貼等等的Menu出現 如果想去除

代碼如下：

public class TextPage extends EditText{    private int off;         public TextPage(Context context, AttributeSet attributeSet)    {        super(context, attributeSet);    }        public TextPage(Context context)    {        super(context);        initView();    }        private void initView()    {        setGravity(Gravity.TOP);        setBackgroundColor(Color.WHITE);    }        @Override    protected void onCreateContextMenu(ContextMenu menu)    {        //阻止長按彈出Menu菜單    }        @Override    public boolean getDefaultEditable()    {        return false;    }        @Override    public boolean onTouchEvent(MotionEvent event)    {        int action = event.getAction();        Layout layout = getLayout();        int line = 0;        switch (action)        {            case MotionEvent.ACTION_DOWN:                line = layout.getLineForVertical(getScrollY() + (int)event.getY());                off = layout.getOffsetForHorizontal(line, (int)event.getX());                Selection.setSelection(getEditableText(), off);                break;            case MotionEvent.ACTION_MOVE:            case MotionEvent.ACTION_UP:                line = layout.getLineForVertical(getScrollY() + (int)event.getY());                int curOff = layout.getOffsetForHorizontal(line, (int)event.getX());                Selection.setSelection(getEditableText(), off, curOff);                break;        }        return true;    }}

 

如果有別的什麼需求說不定也會用到的。
