Question

这是我的代码

    //declare a boolean variable for score
    private int optionTxtView = 0  ;
    
    //Search word 
//display score
    public void viewWord(View view)
    {
        score = (TextView)findViewById(R.id.yourScore);
    	tv2 = (TextView)findViewById(R.id.tv2);
        tv3 = (TextView)findViewById(R.id.tv3);
        searchWord = (ImageView) findViewById(R.id.searchWord);
        wordList = (ListView) findViewById(R.id.wordList);
        text = (AutoCompleteTextView) findViewById(R.id.textHere);
        wordList = (ListView) findViewById(R.id.wordList);
        
        
    	String s1= search.getText().toString();
        String s2= dbHelper.getData(s1);
      
        if(optionTxtView == 0){
        //display the score on textview1
    		tv2.setText(s2);
    		optionTxtView = 1;
    		
    		}
        else{
        //display the score on textview2    
            tv3.setText(s2);
    		optionTxtView = 0;
    		
       	}
        
        calculate();
      
    	ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, new ArrayList<String>());
       	wordList.setAdapter(adapter);   	
    	adapter.add(text.getText().toString());
    	adapter.notifyDataSetChanged();
    	text.setText(null);
    	
    }
	
    
    private void calculate(){
        x = Integer.parseInt(tv2.getText().toString());
        y = Integer.parseInt(tv3.getText().toString());
	    z = x + y;
	    score.setText(Integer.toString(z));
    }

所以基本上我决定有3个textviews，score，tv2和tv3。所以第一个单词的第一个分数应该在tv2中，第二个分数应该在tv3中。这两个textview的总和应该是得分。将文本放在textview上后，它将通过点击图像按钮从数据库中的textview中搜索单词。如果单词在数据库中，它会自动将单词放在listview中，同时它应该在两个textview上显示分数。

我真的需要帮助。我尝试了所有我能做的但是当textview tv2和tv3中的值/数字从属性设置时它永远不会添加EXCEPT。但是，只要数字/值来自数据库（因为它应该是它），它就永远不会添加！

任何帮助都将受到高度赞赏。请帮我处理我的密码。

Answer 1

它永远不会在textview tv2和tv3中的值/数字时添加EXCEPT 是从属性
设置的

您需要将代码放在onClick按钮或监听的任何内容中，以便用户执行操作。之后，您可以获得textview's值并对其执行某些操作。

从代码的外观来看，我建议您移动 onCreate中的所有初始化：

        //move this code to onCreate
        score = (TextView)findViewById(R.id.yourScore);
        tv2 = (TextView)findViewById(R.id.tv2);
        tv3 = (TextView)findViewById(R.id.tv3);
        searchWord = (ImageView) findViewById(R.id.searchWord);
        wordList = (ListView) findViewById(R.id.wordList);
        text = (AutoCompleteTextView) findViewById(R.id.textHere);
        wordList = (ListView) findViewById(R.id.wordList);

    //also move this
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, new ArrayList<String>());
    wordList.setAdapter(adapter);

之后，请致电viewWord()（或您喜欢的任何内容）中的onClick，例如：

 button.setOnClickListener(new OnClickListener() {

    public void onClick(View v) {
        // TODO Auto-generated method stub
        viewWord(v); //v is your button
    }
 });

更新

在查看logcat中的异常之后，似乎发生了错误，因为整数有一些whitespaces：“2”＆lt; - 2之后的空格

尝试：

 x = Integer.parseInt(tv2.getText().toString().replaceAll("\\s",""));
y = Integer.parseInt(tv3.getText().toString().replaceAll("\\s",""));

我们的想法是删除所有空白，然后再将其解析为Integer。
