首先，处理按键按下后，可以通过发送广播让应用层识别按键事件，那么怎么来发送，可以找到下面这个文件:
frameworks/base/policy/src/com/android/internal/policy/impl/PhoneWindowManager.java
对应这个文件，我们找到这个方法，代码很多，部分shenglue
/** {@inheritDoc} */
@Override
public long interceptKeyBeforeDispatching(WindowState win, KeyEvent event, int policyFlags) {
final boolean keyguardOn = keyguardOn();
final int keyCode = event.getKeyCode();
final int repeatCount = event.getRepeatCount();
final int metaState = event.getMetaState();
final int flags = event.getFlags();
final boolean down = event.getAction() == KeyEvent.ACTION_DOWN;
final boolean canceled = event.isCanceled();
if (DEBUG_INPUT) {
Log.d(TAG, "interceptKeyTi keyCode=" + keyCode + " down=" + down + " repeatCount="

+ " canceled=" + canceled);
}
// If we think we might have a volume down & power key chord on the way
// but we're not sure, then tell the dispatcher to wait a little while and
// try again later before dispatching.
if (mScreenshotChordEnabled && (flags & KeyEvent.FLAG_FALLBACK) == 0) {
if (mVolumeDownKeyTriggered && !mPowerKeyTriggered) {
final long now = SystemClock.uptimeMillis();
final long timeoutTime = mVolumeDownKeyTime + SCREENSHOT_CHORD_DEBOUNCE_DELAY_MILLIS;
if (now < timeoutTime) {
return timeoutTime - now;
}
}
if (keyCode == KeyEvent.KEYCODE_VOLUME_DOWN
&& mVolumeDownKeyConsumedByScreenshotChord) {
if (!down) {

}
return -1;
}
}

// can never break it, although if keyguard is on, we do let

// while it was pressed, then it is time to go home!
if (!down) {

if (mHomeConsumed) {
mHomeConsumed = false;
return -1;
}
if (canceled) {
Log.i(TAG, "Ignoring HOME; event canceled.");
return -1;
}
// If an incoming call is ringing, HOME is totally disabled.

if (mDreamManagerInternal != null && mDreamManagerInternal.isDreaming()) {
mDreamManagerInternal.stopDream(false /*immediate*/);
return -1;
}
// Go home!
launchHomeFromHotKey();
return -1;
}比如现在，我们需要添加一个camera button的广播，那么如何来添加呢？ /** {@inheritDoc} */
//添加CamerakeyAction
private String CamerakeyAction = null;
@Override
public long interceptKeyBeforeDispatching(WindowState win, KeyEvent event, int policyFlags) {
final boolean keyguardOn = keyguardOn();
final int keyCode = event.getKeyCode();
final int repeatCount = event.getRepeatCount();
final int metaState = event.getMetaState();
final int flags = event.getFlags();
final boolean down = event.getAction() == KeyEvent.ACTION_DOWN;
final boolean canceled = event.isCanceled();
if (DEBUG_INPUT) {
Log.d(TAG, "interceptKeyTi keyCode=" + keyCode + " down=" + down + " repeatCount="
+ repeatCount + " keyguardOn=" + keyguardOn + " mHomePressed=" + mHomePressed
+ " canceled=" + canceled);
}
if (true ) {
CamerakeyAction = null;
//如果按键事件收到是KEYCODE_CAMERA
if(keyCode == KeyEvent.KEYCODE_CAMERA)
{
//那么定义按键发送的广播标题
CamerakeyAction = "com.camera_k.broadcast.camerabutton";
}
if ( null != CamerakeyAction ) {
mHandler.post( new Runnable() {
public void run() {
//以下为发送广播的内容，当按键按下后
//发送key_code key_action等。
Intent intent = new Intent(CamerakeyAction);
intent.putExtra("key_code", keyCode);
intent.putExtra("key_action", keyAction);
intent.putExtra("repeat_count", repeatCount);
intent.putExtra("device_id", deviceID);
intent.putExtra("down_time", downTime);
intent.putExtra("event_time", eventTime);
intent.putExtra("number", number);
intent.putExtra("flags", flags);
intent.putExtra("scan_code", scanCode);
intent.putExtra("source", source);
intent.putExtra("display_label", displayLabel);
intent.putExtra("meta_state", metaState);
intent.putExtra("unicode_char", unicodeChar);
intent.putExtra("characters", characters);
//发送广播
mContext.sendBroadcast(intent);
}
} );
}
}; 添加完以后，重新编译即可。PhoneWindowManager.java源码：
