手把手教你Tiny4412 Android5.0 定制 按下开发板上的按键通过广播发送到应用层

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

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 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("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。
