android解锁屏幕实例

android解锁屏幕实例

在进行自动化测试中，经常会遇到，黑屏跟需要解锁的情况，如果这种情况不处理，自动化测试无法开始执行，下面是唤醒屏幕跟解锁的方法，代码如下：

package com.hxkid.parent.utils;

import android.annotation.SuppressLint;

import android.app.Instrumentation;

import android.app.KeyguardManager;

import android.app.KeyguardManager.KeyguardLock;

import android.content.Context;

import android.os.PowerManager;

import android.os.PowerManager.WakeLock;

import android.test.InstrumentationTestCase;

import android.util.Log;

@SuppressLint("Wakelock")

@SuppressWarnings("deprecation")

public class Util {

/**

* wake up screen if needed

*

* @param owner

* @

*/

public static WakeLock wakeScreen(InstrumentationTestCase owner) {

PowerManager pm = (PowerManager) owner.getInstrumentation()

.getTargetContext().getSystemService(Context.POWER_SERVICE);

WakeLock wakeLock = pm.newWakeLock(PowerManager.SCREEN_BRIGHT_WAKE_LOCK

| PowerManager.FULL_WAKE_LOCK

| PowerManager.ACQUIRE_CAUSES_WAKEUP, owner.getClass()

.getSimpleName());

wakeLock.acquire();

return wakeLock;

}

/**

*unlock screen if needed

*/

public static void unlock(Instrumentation instr) {

try {

Context targetContext = instr.getTargetContext();

KeyguardManager keyGuardManager = (KeyguardManager) targetContext

.getSystemService(Context.KEYGUARD_SERVICE);

KeyguardLock mLock = keyGuardManager.newKeyguardLock("");

mLock.disableKeyguard();

} catch (Throwable e) {

Log.e("", "disableKeyguard:", e);

}

}

}
