我已经尝试了所有的解决方案，但没有一个解决方案适合我，所以我找到了我的解决方案：您应该有如下布尔变量：

public static isKeyboardShowing = false;
InputMethodManager inputMethodManager = (InputMethodManager) getActivity()
            .getSystemService(Context.INPUT_METHOD_SERVICE);

在触摸屏事件中，您可以拨打：

@Override
public boolean onTouchEvent(MotionEvent event) {
    if(keyboardShowing==true){
        inputMethodManager.toggleSoftInput(InputMethodManager.RESULT_UNCHANGED_HIDDEN, 0);
        keyboardShowing = false;
    }
    return super.onTouchEvent(event);
}

在EditText中的任何位置：

yourEditText.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            yourClass.keyboardShowing = true;

        }
    });

到目前为止，Saurabh Pareek给出了最好的答案。

不过，不妨使用正确的标志。

/* hide keyboard */
((InputMethodManager) getSystemService(Activity.INPUT_METHOD_SERVICE))
    .toggleSoftInput(InputMethodManager.SHOW_IMPLICIT, 0);

/* show keyboard */
((InputMethodManager) getSystemService(Activity.INPUT_METHOD_SERVICE))
    .toggleSoftInput(0, InputMethodManager.HIDE_IMPLICIT_ONLY);

实际使用示例

/* click button */
public void onClick(View view) {      
  /* hide keyboard */
  ((InputMethodManager) getSystemService(Activity.INPUT_METHOD_SERVICE))
      .toggleSoftInput(InputMethodManager.SHOW_IMPLICIT, 0);

  /* start loader to check parameters ... */
}

/* loader finished */
public void onLoadFinished(Loader<Object> loader, Object data) {
    /* parameters not valid ... */

    /* show keyboard */
    ((InputMethodManager) getSystemService(Activity.INPUT_METHOD_SERVICE))
        .toggleSoftInput(0, InputMethodManager.HIDE_IMPLICIT_ONLY);

    /* parameters valid ... */
}

在如此的搜索中，我找到了一个适合我的答案

// Show soft-keyboard:
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);

// Hide soft-keyboard:
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

public void hideKeyboard() 
{
    if(getCurrentFocus()!=null) 
    {
        InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
        inputMethodManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
    }
}


public void showKeyboard(View mView) {
    InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
    mView.requestFocus();
    inputMethodManager.showSoftInput(mView, 0);
}

这对我有用：

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

if (v 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;
}

隐藏软键盘也很有用：

getWindow().setSoftInputMode(
    WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN
);

这可用于抑制软键盘，直到用户实际触摸editText View。
