ActivityTransitionActivity中的启动代码如下 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { ActivityCompat.startActivity..., UtilPair(tvShare, "text") ) ActivityCompat.startActivity...(this, ShareViewActivity::class.java)) } } 需要使用Pair将每组View与transitionName关联，最后调用ActivityCompat
true; try { //一般requestCode都不会为-1，所以不会走if里面 if (requestCode == -1) { ActivityCompat.startActivityForResult...allocateRequestIndex(fragment); //发起startActivityForResult调用，这里requestIndex和requestCode关联起来 ActivityCompat.startActivityForResult...requestIndex; } 这里allocateRequestIndex方法就把requestIndex和Fragment的mWho变量关联起来了 在上面的startActivityFromFragment方法中调用ActivityCompat...requestCode关联起来了 这样后面回调onActivityResult方法时就可以根据requestCode获取对应的Fragment，以便调用Fragment的onActivityResult方法 最后看一下ActivityCompat
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.RECORD_AUDIO) !...= PackageManager.PERMISSION_GRANTED || ActivityCompat.checkSelfPermission(this, Manifest.permission.CAMERA...= PackageManager.PERMISSION_GRANTED || ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE...= PackageManager.PERMISSION_GRANTED || ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE...= PackageManager.PERMISSION_GRANTED) { ActivityCompat.requestPermissions((Activity) this,
verifyStoragePermissions(Activity activity) { // 检查应用程序是否有权写入设备存储 int permission = ActivityCompat.checkSelfPermission...= PackageManager.PERMISSION_GRANTED) { // 如果应用程序没有权限，则会提示用户授予权限 ActivityCompat.requestPermissions
