Abstract

The present invention provides a soft keyboard display method and a mobile terminal, and relates to the field of mobile terminals. The method includes: processing a picture of a soft keyboard by adopting an α blending technology according to a preset transparency parameter, so that the picture of the soft keyboard presents transparency corresponding to the transparency parameter; and displaying a processed picture of the soft keyboard on a current background picture of a mobile terminal touchscreen in a suspended manner when it is detected that the soft keyboard needs to be displayed. The mobile terminal includes: a transparency processing module and a suspended displaying module. The mobile terminal includes: a touchscreen and at least one processor. The processor is coupled with the touchscreen. The processor is configured to perform the function of the soft keyboard display method.

Claims

1. A soft keyboard display method comprising:

processing a picture of a soft keyboard by adopting an Alpha Blending (α

blending) technology according to a preset transparency parameter such that the picture of the soft keyboard'"'"'s transparency corresponds to the preset transparency parameter;

displaying the processed picture of the soft keyboard on a current background picture of a mobile terminal touchscreen in a suspended manner when it is detected that the soft keyboard needs to be displayed; and

setting the preset transparency parameter to a value that differs from an alpha value used in the α

blending technology.

2. The method according to claim 1, wherein after displaying the processed picture of the soft keyboard on the current background picture of the mobile terminal touchscreen in the suspended manner, the method further comprises hiding the processed picture of the soft keyboard when a click, a slide, or both are detected in a non-soft-keyboard area of the mobile terminal.

3. The method according to claim 1, wherein after displaying the processed picture of the soft keyboard on the current background picture of the mobile terminal touchscreen in the suspended manner, the method further comprises hiding the picture of the soft keyboard when a slide along a preset track is detected in a soft keyboard area of the mobile terminal.

4. The method according to claim 1, wherein after displaying the processed picture of the soft keyboard on the current background picture of the mobile terminal touchscreen in the suspended manner, the method further comprises hiding the picture of the soft keyboard when a click is detected in a preset area of the soft keyboard of the mobile terminal.

5. The method according to claim 1, wherein the value of the preset transparency parameter ranges from zero to one, excluding zero and one.

6. The method according to claim 1, further comprising adjusting the preset transparency parameter to a second value that differs from the alpha parameter used in the α

blending technology.

7. A mobile terminal comprising:

a touchscreen; and

at least one processor,

wherein the processor is coupled with the touchscreen,

wherein the processor is configured to process a picture of a soft keyboard by adopting an α

blending technology according to a preset transparency parameter such that the picture of the soft keyboard'"'"'s transparency corresponds to the preset transparency parameter,

wherein a processed picture of the soft keyboard is displayed on a current background picture of the touchscreen in a suspended manner when it is detected that the soft keyboard needs to be displayed, and

wherein the preset transparency parameter is set to a value that differs from an alpha value used in the α

blending technology.

8. The mobile terminal according to claim 7, wherein the processor is further configured to hide the picture of the soft keyboard when a click, a slide, or both are detected in a non-soft-keyboard area of the touchscreen.

9. The mobile terminal according to claim 7, wherein the processor is further configured to hide the picture of the soft keyboard when a slide along a preset track is detected in a soft keyboard area of the touchscreen.

10. The mobile terminal according to claim 7, wherein the processor is further configured to hide the picture of the soft keyboard when a click is detected in a preset area of the soft keyboard of the touchscreen.

11. The mobile terminal according to claim 7, wherein the value of the preset transparency parameter ranges from zero to one, excluding zero and one.

12. The mobile terminal according to claim 7, wherein the processor is further configured to adjust the preset transparency parameter to a second value that differs from the alpha parameter used in the α

blending technology.
