我是新来的，如果我犯错误就很抱歉。我也是来自德国，对不好的英语感到抱歉。
我的代码有两个问题。 第一个是整数列表“my”每次获得相同的Integer，第二个问题是当我第二次按下开始按钮时for循环不起作用。 这是我的代码：
public class MainActivity extends AppCompatActivity implements MediaPlayer.OnCompletionListener {
String text;
MediaPlayer mp;
int i;
List<Integer> my=new ArrayList<Integer>();;
int load;
int an=0;
String[] help;
boolean existing=false;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn=(Button) findViewById(R.id.button);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
EditText ed=(EditText) findViewById(R.id.editText);
text=ed.getText().toString();
tts();
}
});
Button lös=(Button) findViewById(R.id.button6);
lös.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
EditText ed=(EditText) findViewById(R.id.editText);
ed.setText("");
}
});
}
public void tts(){
if (text.isEmpty()){
Toast.makeText(this,"Gib erstmal was zum aussprechen ein!",Toast.LENGTH_SHORT).show();
}

答案 0 :(得分：0)
你有
i = 0;
mp = MediaPlayer.create(this, my.get(i));
所以它总是得到元素0一个i只有0（第一个）。
您已在中指定变量作为循环计数器，但在循环中使用了 i ，例如你有
for (int in = 0; in < help.length; in++) {
if (help[i].equals("40")) {
an = R.raw.a40;
my.add(an);
} .........
}
将循环中 i 的每次出现更改为或int in = 0; in < help.length; in++更改为int i = 0; i < help.length; i++
