思路:

第一种方案：屏蔽除power外的其他按键，屏蔽状态栏下拉，屏蔽触屏。
代码如下：

需要系统签名：
添加权限:
<uses-permission android:name="android.permission.STATUS_BAR" />
<uses-permission android:name="android.permission.EXPAND_STATUS_BAR" />

package com.example.demo;

import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.Menu;
import android.util.Log;
import android.view.Window;
import android.view.WindowManager;
import android.app.StatusBarManager;
import android.view.MotionEvent;
public class MainActivity extends Activity {
public static final int FLAG_HOMEKEY_DISPATCHED = 0x80000000;
private StatusBarManager mStatusBarManager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
getWindow().addFlags(FLAG_HOMEKEY_DISPATCHED); //禁止home
disableStatusbar();// 禁止状态栏
setContentView(R.layout.activity_main);

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
// getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onTouchEvent(MotionEvent event) {
// TODO Auto-generated method stub
return true;
}
private void disableStatusbar(){
// 第一句是否可以提出去

mStatusBarManager = (StatusBarManager) this.getSystemService(this.STATUS_BAR_SERVICE);
mStatusBarManager.disable(StatusBarManager.DISABLE_EXPAND);
}

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
// TODO Auto-generated method stub
switch (keyCode) {
case KeyEvent.KEYCODE_VOLUME_DOWN:
case KeyEvent.KEYCODE_VOLUME_UP:
case KeyEvent.KEYCODE_HOME:
return true;

default:
break;
}
return super.onKeyDown(keyCode, event);
}

@Override
public boolean onKeyLongPress(int keyCode, KeyEvent event) {
// TODO Auto-generated method stub
switch (keyCode) {
case KeyEvent.KEYCODE_VOLUME_DOWN:
case KeyEvent.KEYCODE_VOLUME_UP:
case KeyEvent.KEYCODE_HOME:
return true;

default:
break;
}
return super.onKeyLongPress(keyCode, event);
}

@Override
public void onBackPressed() {
// TODO Auto-generated method stub
// super.onBackPressed();
}

}

如此下来，可以模拟除了power外的所有操作。

2：
以上行为，没法屏蔽power，下面方案实现屏蔽power
这里使用了am命令操作.

具体操作：进入cmd 输入adb shell进入终端

am hang 即可。

3：使用apk实现am命令方案:
runCommand("am hang");
private boolean runCommand(String command) {
java.lang.Process process = null;
try {
process = Runtime.getRuntime().exec(command);
Log.i("lxm", "Runtime");
process.waitFor();
} catch (Exception e) {
e.printStackTrace();
Log.i("lxm", "error");
return false;
} finally {
try {
process.destroy();
} catch (Exception e) {

}
}
Log.i("lxm", "finally");
return true;
}

需要添加权限:
<uses-permission android:name="android.permission.SET_ACTIVITY_WATCHER" />
具体代码可以查看activitymanagerserver.java 里面的hang函数。

4:完整apk源码为：
AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.demo"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="18" />

<uses-permission android:name="android.permission.STATUS_BAR" />
<uses-permission android:name="android.permission.EXPAND_STATUS_BAR" />
<uses-permission android:name="android.permission.SET_ACTIVITY_WATCHER" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/hello_world"
android:screenOrientation="portrait"
android:theme="@style/AppTheme" >
<activity
android:name="com.example.demo.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

</manifest>

MainActivity.java

package com.example.demo;

import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.Menu;
import android.util.Log;
import android.view.Window;
import android.view.WindowManager;
import android.app.StatusBarManager;
import android.view.MotionEvent;
public class MainActivity extends Activity {
public static final int FLAG_HOMEKEY_DISPATCHED = 0x80000000;
private StatusBarManager mStatusBarManager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
getWindow().addFlags(FLAG_HOMEKEY_DISPATCHED);
disableStatusbar();
setContentView(R.layout.activity_main);
java.lang.Process process = null;
runCommand("am hang");
}
private boolean runCommand(String command) {
java.lang.Process process = null;
try {
process = Runtime.getRuntime().exec(command);
Log.i("lxm", "Runtime");
process.waitFor();
} catch (Exception e) {
e.printStackTrace();
Log.i("lxm", "error");
return false;
} finally {
try {
process.destroy();
} catch (Exception e) {

}
}
Log.i("lxm", "finally");
return true;
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
// getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onTouchEvent(MotionEvent event) {
// TODO Auto-generated method stub
return true;
}
private void disableStatusbar(){
// 第一句是否可以提出去

mStatusBarManager = (StatusBarManager) this.getSystemService(this.STATUS_BAR_SERVICE);
mStatusBarManager.disable(StatusBarManager.DISABLE_EXPAND);
}

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
// TODO Auto-generated method stub
switch (keyCode) {
case KeyEvent.KEYCODE_VOLUME_DOWN:
case KeyEvent.KEYCODE_VOLUME_UP:
case KeyEvent.KEYCODE_HOME:
return true;

default:
break;
}
return super.onKeyDown(keyCode, event);
}

@Override
public boolean onKeyLongPress(int keyCode, KeyEvent event) {
// TODO Auto-generated method stub
switch (keyCode) {
case KeyEvent.KEYCODE_VOLUME_DOWN:
case KeyEvent.KEYCODE_VOLUME_UP:
case KeyEvent.KEYCODE_HOME:
return true;

default:
break;
}
return super.onKeyLongPress(keyCode, event);
}

@Override
public void onBackPressed() {
// TODO Auto-generated method stub
// super.onBackPressed();
}

}

android.mk 为:
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)

LOCAL_MODULE_TAGS := optional

LOCAL_SRC_FILES := $(call all-java-files-under, src)

#LOCAL_STATIC_JAVA_LIBRARIES := com.android.phone.common

LOCAL_PACKAGE_NAME := Frozen
LOCAL_CERTIFICATE := platform

#LOCAL_PROGUARD_FLAG_FILES := proguard.flags

include $(BUILD_PACKAGE)

# Use the folloing include to make our test apk.
include $(call all-makefiles-under,$(LOCAL_PATH))
