Analysis of Jitter Input Box and Mobile Phone Vibration of Android Mobile Phone Guardian

Look at apiDemos, find View/Animation/shake, find the corresponding animation code, and copy it directly

When importing a project, the report 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);

Animated xml file shake. xml

android:interpolator="@anim/cycle_7"

interpolator is an inserter, which can define the speed of animation and so on

Call the setInterpolator () method of the Animation object to set the inserter, parameter: Interpolator object

Anonymously implement Interpolator interface, override getInterpolation () method, set custom animation rate, pass in 1 flaot x

Vibration effect of input box

Get the Vibrator object, call the getSystemService () method, parameter: VIBRATOR_SERVICE

Call the vibrate () method of the Vibrator object, argument: milliseconds

Need to add permissions android. permission. VIBRATE

This can be used as a vibrator ~

/**

public void queryNumber(View v) {
phone = et_phone.getText().toString().trim();
if (TextUtils.isEmpty(phone)) {
// Jitter animation 
Animation shake = AnimationUtils.loadAnimation(this, R.anim.shake);
et_phone.startAnimation(shake);
// Mobile phone vibration 
vibrator.vibrate(2000);
Toast.makeText(this, " Please enter your mobile phone number ", 0).show();
return;
}
String result = NumberQueryAddressUtil.queryAddress(phone);
tv_address.setText(result);
}

The above is the site to introduce the Android mobile phone guard of the input box jitter and mobile phone vibration related content, I hope to help you!
