解决 sdk 4.0 以上屏蔽系统输入法以后不显示光标的Bug; Shielding system soft keyboard does not display the EditText cursor Bug.

code

        if (android.os.Build.VERSION.SDK_INT <= 10) {   //2.3版本之前使用此方法
            edit.setInputType(InputType.TYPE_NULL);
        } else {    //2.3版本以后用反射方法设置setSoftInputShownOnFocus(4.0)的值解决
            getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
            try {
                    Class<EditText> cls = EditText.class;
                    Method setSoftInputShownOnFocus;
                    setSoftInputShownOnFocus = cls.getMethod("setSoftInputShownOnFocus", boolean.class);
                    setSoftInputShownOnFocus.setAccessible(true);
                    setSoftInputShownOnFocus.invoke(edit, false);
            } catch (Exception e) {
                    e.printStackTrace();
            }
            try {   // 有部分SDK的方法名字为setShowSoftInputOnFocus(4.2) 
                    Class<EditText> cls = EditText.class;
                    Method setShowSoftInputOnFocus;
                    setShowSoftInputOnFocus = cls.getMethod("setShowSoftInputOnFocus", boolean.class);
                    setShowSoftInputOnFocus.setAccessible(true);
                    setShowSoftInputOnFocus.invoke(edit, false);
            } catch (Exception e) {
                    e.printStackTrace();
            }
        }
