Android：如何在强制打开时强制关闭软键盘？

Android:How do I force the soft keyboard to close when it has been forced to open?

我的Activity中有一个EditText。一旦Activity开始，我就强制使用软键盘打开。

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
if (imm != null) {
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
}

现在，如果软键盘打开，我按下主页按钮，它仍保持打开状态。如何在家用印刷机上强行关闭它？

@Override
public boolean dispatchTouchEvent(MotionEvent event) {
View view = getCurrentFocus();
boolean ret = super.dispatchTouchEvent(event);

if (view instanceof EditText) {
View w = getCurrentFocus();
int scrcoords[] = new int[2];
w.getLocationOnScreen(scrcoords);
float x = event.getRawX() + w.getLeft() - scrcoords[0];
float y = event.getRawY() + w.getTop() - scrcoords[1];

// Log.d("Activity","Touch event"+event.getRawX()+","+event.getRawY()+""+x+","+y+" rect"+w.getLeft()+","+w.getTop()+","+w.getRight()+","+w.getBottom()+" coords"+scrcoords[0]+","+scrcoords[1]);
if (event.getAction() == MotionEvent.ACTION_UP && (x < w.getLeft() || x >= w.getRight() || y < w.getTop() || y > w.getBottom()) ) {
InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(getWindow().getCurrentFocus().getWindowToken(), 0);
}
}
return ret;
}

当您触摸屏幕上的任何位置时，此代码会关闭键盘。
