高通Android 12/Android 13截屏

正常截屏Power+音量-键组合键同时长按，实现截屏逻辑。

PhoneWindowManager #init #interceptScreenshotChord

复制代码

init(Context context, IWindowManager windowManager,
            WindowManagerFuncs windowManagerFuncs)

2、在PhoneWindowManager中init方法中注册广播

frameworks/base/services/core/java/com/android/server/policy/PhoneWindowManager.java

复制代码

        // zm fix
		IntentFilter screenfilter = new IntentFilter();
        screenfilter.addAction("android.intent.action.SCREEN_SHOT");
		context.registerReceiver(mScreenshotReceiver, screenfilter);

3、广播实现代码如下图所示

复制代码

    private BroadcastReceiver mScreenshotReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        if ("android.intent.action.SCREEN_SHOT".equals(intent.getAction())) {
			Log.e("Receive Screen Shot Action","Screen Shot="+intent.getAction());
			String path = intent.getStringExtra("path");
            Log.e("onReceive", "Screenshot path: " + path);
            interceptScreenshotChord();
			copyLatestFile("/sdcard/Pictures/Screenshots",path);
			Log.e("onReceive", "Screenshot path completed: " + path);
			
        }
    }
};

4、自定义Service里面发送广播代码如下所示

复制代码

 /**
     * 截屏
     *
     * @param path
     */
    public boolean capture(String path) {
		Log.e("capture","=========start capture=============");
		Intent intent = new Intent("android.intent.action.SCREEN_SHOT");
		intent.putExtra("path", path);
        mContext.sendBroadcast(intent);
	 
    }

5、PhoneWindowManager中调用是发广播到 PhoneWindowManager interceptScreenshotChord中调用，具体源码细节，大家感兴趣去源码跟下哈，这里不再赘述哈。

复制代码

    private void interceptScreenshotChord() {
        mHandler.removeCallbacks(mScreenshotRunnable);
        mScreenshotRunnable.setScreenshotType(TAKE_SCREENSHOT_FULLSCREEN);
        mScreenshotRunnable.setScreenshotSource(SCREENSHOT_KEY_CHORD);
        mHandler.postDelayed(mScreenshotRunnable, getScreenshotChordLongPressDelay());
    }

6、最后截屏具体实现代码逻辑如下所示

复制代码

private class ScreenshotRunnable implements Runnable {
        private int mScreenshotType = TAKE_SCREENSHOT_FULLSCREEN;
        private int mScreenshotSource = SCREENSHOT_KEY_OTHER;

        public void setScreenshotType(int screenshotType) {
            mScreenshotType = screenshotType;
        }

        public void setScreenshotSource(int screenshotSource) {
            mScreenshotSource = screenshotSource;
        }

        @Override
        public void run() {
            mDefaultDisplayPolicy.takeScreenshot(mScreenshotType, mScreenshotSource);
        }
    }

    private final ScreenshotRunnable mScreenshotRunnable = new ScreenshotRunnable();
