[Android] mobile guard input box jitter and mobile phone vibration

• Android

Check apidemos, find view / animation / shake, find the corresponding animation code, and copy it directly

When importing a project, it is reported that the R file does not exist. In many cases, the XML file is wrong

Animation shake = AnimationUtils.loadAnimation(this,R.anim.shake);

et_ phone.startAnimation(shake);

The XML file for animation is shake.xml

android:interpolator="@anim/cycle_7"

Interpolator is an inserter, which can define the speed of animation, etc

Call the setinterpolator () method of the animation object to set the inserter. Parameters: interpolator object

Implement the interpolator interface anonymously, override the getinterpolation () method, set the custom animation rate in, and pass in a flaot X

Vibration effect of input box

Get the vibrator object, call getsystemservice () method, parameter: vibrator_ SERVICE

Call the vibrate() method of the vibrator object, parameter: ms

The permission android.permission.vibrate needs to be added

This can make some vibrators~
