Android/Java变量超出范围可能

当我运行下面的代码时，一切都变好，直到我改变seekBar的值。 onProgressChange更改myValue的文本值。我得到一个关闭的力量，它给了我下面的日志猫条目。Android/Java变量超出范围可能

在进行调试时，抛出的异常说它找不到ID 2，你可以告诉它是myValue，这是预期的。请让我知道你在想什么。感谢

ColorsActivity（主）

public class ColorsActivity extends Activity

CustomSeekBar red = new CustomSeekBar(); 
RelativeLayout theItem; 

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    setContentView(R.layout.seekbarlist);

CustomSeekBar

public class CustomSeekBar implements SeekBar.OnSeekBarChangeListener { 

    Context myContext;

    TextView myValue; 
    TextView myLabel; 
    SeekBar mySeekBar;

    mySeekBar = new SeekBar(myContext); 
    myLabel = new TextView(myContext); 
    myValue = new TextView(myContext); 

    mySeekBar.setId(1); 
    myLabel.setId(2); 
    myValue.setId(3); 

    RelativeLayout.LayoutParams mySeekBarParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);

    RelativeLayout.LayoutParams myValueParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT); 

    int seekBarId = mySeekBar.getId(); 
    int labelId = myLabel.getId(); 

    myLabelParams.addRule(RelativeLayout.BELOW,seekBarId); 
    myValueParams.addRule(RelativeLayout.BELOW,seekBarId); 
    myValueParams.addRule(RelativeLayout.RIGHT_OF,labelId); 

    mySeekBar.setLayoutParams(mySeekBarParams); 
    myLabel.setLayoutParams(myLabelParams); 
    myValue.setLayoutParams(myValueParams); 

    myLabel.setText(label); 
    myValue.setText("hello");  
    mySeekBar.setOnSeekBarChangeListener(this); 

    myLayout.addView(myLabel); 
    myLayout.addView(myValue); 
    myLayout.addView(mySeekBar); 


    return myLayout; 

} 

public void onProgressChanged(SeekBar seekBar, int progress, boolean fromTouch) { 
    myValue.setText(progress);  
    //Amarino.sendDataToArduino(myContext, "00:11:11:21:05:53", 'A', progress); 
} 
public void onStopTrackingTouch(SeekBar seekBar){ 

} 
public void onStartTrackingTouch (SeekBar seekBar){ 
} 


}

要设置文本为int，因此Android认为你正试图通过ID引用的资源。将progress转换为字符串应该可以解决您的问题。例如。 Integer.toString(progress)。
