Android修炼之道—获取软键盘的高度

自动弹出软键盘

  editText = (EditText) findViewById(R.id.edit_text);
  editText.setFocusable(true); 
  editText.setFocusableInTouchMode(true); 
  editText.requestFocus(); 

  InputMethodManager  imm = imm.showSoftInput(
  edtsearch_title, InputMethodManager.RESULT_SHOWN); 

  imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY);

关闭软键盘

//方法1：
 ((InputMethodManager) getSystemService(INPUT_METHOD_SERVICE))
                  .hideSoftInputFromWindow(
                    getCurrentFocus().getWindowToken(),
                    InputMethodManager.HIDE_NOT_ALWAYS);
//方法2：
  InputMethodManager imm = (InputMethodManager) view.getContext()
                   .getSystemService(Context.INPUT_METHOD_SERVICE);
  if (imm.isActive()) {
  imm.hideSoftInputFromWindow(view.getApplicationWindowToken(),
     0);

如何获取软键盘的高度

    final RelativeLayout myLayout = 
        (RelativeLayout)findViewById(R.id.rootview);
    myLayout.getViewTreeObserver().
        addOnGlobalLayoutListener(new 
        ViewTreeObserver.OnGlobalLayoutListener() {
            /**
             * the result is pixels
             */
            @Override
            public void onGlobalLayout() {

                Rect r = new Rect();
                myLayout.getWindowVisibleDisplayFrame(r);

                int screenHeight = myLayout.getRootView().getHeight();
                int heightDifference = screenHeight - (r.bottom - r.top);
                Log.e("Keyboard Size", "Size: " + heightDifference);

                //boolean visible = heightDiff > screenHeight / 3;
            }
        });
