Android：如何强制打开软键盘时强制关闭软键盘？

Question

我有一个EditText在我的Activity。只要Activity开始，我强制软键盘打开使用。

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

现在，如果软键盘已打开，并且按Home键，它仍保持打开状态。我如何在家庭媒体上强制关闭它？

Answer 1

InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE); 
mgr.hideSoftInputFromWindow(Your Button.getWindowToken(), 0); 

Answer 2

@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; 
} 

此代码关闭时你在任何地方触摸屏幕上的键盘。
