Question

我是Android编程新手。我需要一个启发我的Android应用程序。我不知道什么是错的，但当我按下我的＆＃34;计算＆＃34;按钮，它将停止工作（崩溃）。我的程序是关于FLAMES游戏的，你在每个实例中计算一个字符串的字符在另一个字符串中相交。我希望了解更多，每一个帮助将不胜感激。谢谢！

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    Button button1 = (Button) findViewById(R.id.button);
    button1.setOnClickListener(new View.OnClickListener() {
     public void onClick(View v) {
         EditText edittext1 =  (EditText) findViewById(R.id.editText);
         final String name1 = edittext1.toString().replaceAll("\\s+","");
         EditText edittext2 = (EditText) findViewById(R.id.editText2);
         final String name2 = edittext2.toString().replaceAll("\\s+","");
         final TextView result = (TextView) findViewById(R.id.textView);

         int common = 0;
         int resultS = common % 6;

         if (name1.length() > name2.length()){

             for (int i = 0; i < name1.length(); i++) {
                 for (int j = 0; j < name2.length(); j++) {
                     if (name1.charAt(i) == name2.charAt(j)) {
                         common++;

                     }
                         result.setText(resultS);
                 }
             }


         }

         if(name2.length() > name1.length())
         {

             for (int i = 0; i < name2.length(); i++) {
                 for (int j = 0; j < name1.length(); j++) {
                     if (name2.charAt(i) == name1.charAt(j)) {
                         common++;

                     }
                     result.setText(resultS);


                 }


             }

         }

    }
});

logcat的：

Answer 1

  result.setText(String.valueOf(resultS));

因为textview期望一个字符串，你将参数作为整数发送也result.setText(""+resultS);应该有效（这个没有经过测试）

Android应用程序一直停止
