多重搜索欄

我已經實現了多個搜索欄在Android中像多重搜索欄

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

    sb1=(SeekBar) findViewById(R.id.seekBar1); 
    sb2=(SeekBar) findViewById(R.id.seekBar2); 
    sb3=(SeekBar) findViewById(R.id.seekBar3); 

    tv1=(TextView) findViewById(R.id.textView1); 
    tv2=(TextView) findViewById(R.id.textView2); 
    tv3=(TextView) findViewById(R.id.textView3); 

    sb1.setOnSeekBarChangeListener(this); 
    sb2.setOnSeekBarChangeListener(this); 
    sb3.setOnSeekBarChangeListener(this); 

} 

@Override 
public void onProgressChanged(SeekBar arg0, int arg1, boolean arg2) 
{ 

    switch (arg0.getId()) 
    { 
    case R.id.seekBar1: 
     tv1.setText(arg1); 
     break; 
    case R.id.seekBar2: 
     tv2.setText(arg1); 
     break; 
    case R.id.seekBar3: 
     tv3.setText(arg1); 
     break; 
    } 
} 

@Override 
public void onStartTrackingTouch(SeekBar arg0) 
{ 
    // TODO Auto-generated method stub 

} 

@Override 
public void onStopTrackingTouch(SeekBar arg0) 
{ 
    // TODO Auto-generated method stub 

}

每當我運行這個程序，它提供了以下錯誤：

我不知道爲什麼會發生這種情況。請幫幫我。提前感謝

感謝薩米爾編輯此。我可以知道你是如何改變這種格式的logcat錯誤嗎 – Khushi 2012-07-18 10:52:32

您正在將int傳入您的TextView的setText()方法，該方法是使用該ID查找資源的重載。你需要改變它（以及類似的線）：

tv1.setText(arg1.toString());

感謝很多cjk它爲我工作..... – Khushi 2012-07-18 10:50:21

我們必須將整數轉換爲字符串：使用tv1.setText（Integer.toString（arg1））或tv1。 setText（「」+ arg1） – Khushi 2012-07-19 10:53:39

或我的方式，這通常是首選的方式... – cjk 2012-07-19 13:18:06

我們可以使用下面的解決方案：

1. tv1.setText(Integer.toString(arg1)) 
2. tv1.setText(""+arg1)
