问题描述

hi
我写这段代码

hi i'm write this code

public class MainActivity extends Activity {
    Button btn;
    EditText et;
     TextView tv;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        btn =(Button)findViewById(R.id.button);
        et =(EditText)findViewById(R.id.editText);
        tv =(TextView)findViewById(R.id.textView);

        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String name =et.getText().toString();
                String a = "a";
                String a1 = "\u00E1";
                String b = "b";
                String b1 = "\u00DF";

                if(name.equals(a)){
                 tv.setText(a1);

                }
                else if (name.equals(b)){
                    tv.setText(b1);

                }
            }
        });

    }
}

当写一个编辑文本写字符时

和写b时在编辑文字写字符

，但当我写ab或ba不写字符



我尝试过：



i不知道写在这里什么

i不知道写什么

and when write a in edit text write character
and when write b in edit text write character
but when i'm write ab or ba dont write character

What I have tried:

i don't know what write here
i don't know what write here

推荐答案

最后看看你的 if 子句：你的代码只放入 tv 如果输入是a或b。没有考虑其他条件。

Look at your if clause at the end: your code only puts something in tv if the input is "a" or "b". No other conditions are considered.

我想写ab显示字符串a1和b1以及写ba写​​字符串b1和字符串a1

i want when write ab show string of a1 and b1 and when write ba write string b1 and string a1
