Further, in above-mentioned steps 102, detect the second trigger event produced on the first contact, obtain the position of starting mark, following three kinds of implementations can be adopted:
It should be noted that, before above-mentioned steps 102, also comprise the steps:
Detect header or footer that whether the first contact moves to current page.
When detecting that the first contact does not move to header or the footer of current page, according to mode one and mode two have obtained the position of point identification below.
When detecting that the first contact has moved to header or the footer of current page, obtain the position of point identification according to mode three below.
Mode one,
Detect the second trigger event produced on described first contact, directly obtain the position of position as starting mark of the first contact.
Be specially: detect the UP event produced on the first contact, directly obtain the position of position as starting mark of the first contact.
Such as, when user uses finger or touch tool after touch-screen viewing area is double-clicked, when lifting immediately for second time, terminal obtains the position of the first contact.
And for example, do not lift for second time after user uses finger or touch tool carries out double-click on the touchscreen, and drag when lifting after starting mark moves on the text of current display again, terminal obtains the first contact position.
In the present embodiment, position during the first contact generation UP event is represented by coordinate, the initial point that this coordinate is corresponding be user use finger or touch tool trigger first contact produce double-click event time the first contact position, the position of any point on touch-screen all can adopt and represent relative to the coordinate of this initial point.If user performs after using finger or touch tool to double-click on the touchscreen and lifts immediately, then the first contact position is above-mentioned origin position.If user uses finger or touch tool to carry out double-click on the touchscreen and do not lift for latter second time, and drag when lifting after starting mark moves on the text of current display, so the first contact position is the coordinate position relative to above-mentioned initial point again.
The position when position of above-mentioned starting mark produces UP event by the first contact and now the first place, the contact line number of line position in whole text are determined.The line number of line position in text at this place, the first contact directly can get with reference to prior art.
Method two,
As shown in Figure 2, method two specifically comprises the steps:
21: the sliding trace detecting the 4th contact that user touches on the touchscreen, obtain the sliding speed of the 4th contact.
First, detect the sliding trace that the 4th contact that user on touch-screen touches produces, obtain the 4th contact and produce time of sliding trace and the sliding trace vertical range relative to touch-screen.
Wherein, the time obtaining the 4th contact generation sliding trace is specially: when the 4th contact of user's touch on touch-screen being detected, terminal starts timing, until stop timing when detecting that the 4th contact that on touch-screen, user touches frames out, this period is the time that the 4th contact produces sliding trace.
Such as, when the finger that user uses or touch tool are left from starting mark, and user use other finger or the touch tool optional position on the touchscreen except the first contact carry out slip touch time, when user starts to carry out slip touch, terminal detects the 4th contact, start timing, until stop timing when detecting and leave from the 4th contact after the finger of user or touch tool are slided, this period is the time S that the 4th contact produces sliding trace, can be expressed as S millisecond.
Wherein, obtain the 4th contact generation sliding trace to be specially relative to the vertical range of touch-screen: sliding trace is the distance that sliding trace projects on the frame parallel with page turning direction relative to the vertical range of touch-screen, touch-screen viewing area such as shown in Fig. 3, the direction of arrow shown in figure is the direction that text carries out page turning, line segment between A point and B is the sliding trace of the 4th contact, the distance of line segment A ' B ' that then line segment AB projects on Right Border is the vertical range of sliding trace relative to touch-screen, it should be noted that, this figure just schematically, page turning direction can also be downwards, to the left or to the right.
Such as, when user uses finger or touch tool to keep touching on starting mark, and when using other finger or touch tool to lift after sliding in the optional position of touch-screen, the sliding trace L of the 4th contact detected, L pixel can be expressed as.
Then, sliding trace is produced divided by the 4th contact the sliding speed that time of sliding trace obtains the 4th contact relative to the vertical range of touch-screen, and the sliding speed of the 4th contact is for adjusting the page-turning speed of text.
Wherein, the sliding speed of the 4th contact can be expressed as V=L/S (pixel/millisecond).
In the present embodiment, the page-turning speed of above-mentioned sliding speed adjustment text is specially: using the sliding speed of above-mentioned 4th contact as initial value, text page-turning speed time per unit at the uniform velocity successively decreases, until sliding speed is decremented to 0, text stops page turning; Such as:
Sliding speed every millisecond is successively decreased A pixel/millisecond, then the page-turning speed of text and the pass of time are: V1=V-At, and when sliding speed is decremented to 0, text stops page turning, and wherein, t is the time of text page turning.
22: control text according to the sliding speed of the 4th contact and carry out page turning.
It should be noted that, terminal also carrys out display page page turning according to the sliding speed of the 4th contact, so that user's viewing.
23: detect the second trigger event produced on the first contact, the position of starting mark is obtained according to the sliding speed of the 4th contact.
Concrete, as shown in Figure 4, this step 23 specifically comprises:
23S1: detect the second trigger event produced on the first contact, obtain the position of the first contact.
Such as, when the finger of user or touch tool are lifted in terminal mark, terminal obtains the UP event of the first contact, and namely the position of the first contact is the position of user when using finger or touch tool to lift on starting mark.
23S2: after obtaining the sliding screen operation of execution according to the sliding speed of the 4th contact, the first trip of the first place, contact page is arranged in the line number of whole text.
