关于android：处理在键盘上输入和搜索键


Handling Enter and search key on the keyboard

嗨，我想如果有人有关于谷歌键盘的想法，当你在搜索中输入网址时显示搜索图标，当你输入短信或评论那里像fb或EditText这样的地方时，它会显示Backspace照片以供参考This one show search button。
所以下面的代码正在工作，我想添加
与这些键一起输入按钮，当我在网址中输入此键盘时，我无法按Enter键显示结果在whatsapp和其他应用程序中工作但不在浏览器中。

this one show backspace

        commitTyped(getCurrentInputConnection());

    playClick(primaryCode);
    Keyboard current;

            current = this.keyboard;
        } else {

        }
        this.kv.setKeyboard(current);
        if (current == this.symbols) {
            current.setShifted(false);
        }
    } else if (primaryCode == -6) {
        if (this.kv.getKeyboard() == this.eng_keyboard) {
            current = this.keyboard;
        } else {
            current = this.eng_keyboard;
        }
        this.kv.setKeyboard(current);
    }else if (primaryCode == -10) {
        if (this.kv.getKeyboard() == this.keyboard) {
            current = this.eng_keyboard;
        } else {
            current = this.keyboard;
        }
        this.kv.setKeyboard(current);
    }else {
        handleCharacter(primaryCode, keyCodes);
    }
}

那些键工作我想在输入url区域时添加输入/搜索键

}

我不得不创建两个不同的键盘xml，一个带有输入按钮，另一个带有退格键。 我必须输入带有退格按钮apear的edittext键盘，当在搜索栏中输入然后输入按钮apear键盘。
