在我的应用程序中，我动态生成一个包含编辑文本和一些按钮的线性布局。

我希望当用户按下设备键盘上的“输入”时，键盘应该隐藏

我通过设置 edittext 的输入类型来尝试它，但是当用户按下“enter”时，它会移动到另一个 edittext 。

我怎样才能做到这一点？？

尝试以下操作：

final EditText et = new EditText(this);
        et.setId(id[i][0]);
        et.setTextSize(TypedValue.COMPLEX_UNIT_SP, 15);
        et.setTypeface(Typeface.SERIF);

et.setOnKeyListener(new View.OnKeyListener()
        {

            @Override
            public boolean onKey(View editView, int keyCode, KeyEvent event)
            {
                Context mContext = Page1.this;
                if( keyCode == KeyEvent.KEYCODE_ENTER ){
                    et.clearFocus();
                    InputMethodManager imm = (InputMethodManager) mContext.getSystemService(Context.INPUT_METHOD_SERVICE);
                    imm.hideSoftInputFromWindow(et.getWindowToken(),0);
                    return true;
                }
                return false;
            }
        })
