发送搜索条的值，而不是文本字符串

Question

我基础上，BluetoothChat例子，我有2个按钮的主要活动开发一个应用程序：

1. Find devices 
2. Configuration 

随着第一个按钮，我要寻找的代码相同的设备如在上述例子中那样。

在第二按钮就会进入到另一个活动，其中i有3个seekbars与每一个表示当前搜索条的值下textviews。

我需要的是修改BluetoothChat示例的代码，使用这3个值而不是文本发送数组。

这是这个活动的代码，我正在试图开发这个。

我该怎么做？

/*********************

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

    bar1 = (SeekBar)findViewById(R.id.fastbar); 
    bar1.setOnSeekBarChangeListener(this); 
    progress1 = (TextView)findViewById(R.id.out1); 

    bar2 = (SeekBar)findViewById(R.id.climbbar); 
    bar2.setOnSeekBarChangeListener(this); 
    progress2 = (TextView)findViewById(R.id.out2); 

    bar3 = (SeekBar)findViewById(R.id.platformbar); 
    bar3.setOnSeekBarChangeListener(this); 
    progress3 = (TextView)findViewById(R.id.out3); 

    mPreferences = PreferenceManager.getDefaultSharedPreferences(this); 

    /**Initialize the buffer for outgoing messages*/ 
    GlobalVar.mOutStringBuffer = new StringBuffer(""); 
}

    switch (bar.getId()) { 
     case R.id.fastbar: 
      progress1.setText(progress + "%"); 
      break; 
     case R.id.climbbar: 
      progress2.setText(progress + "%"); 
      break; 
     case R.id.platformbar: 
      progress3.setText(progress + "%"); 
      break; 
    } 
} 

@Override 
public void onStartTrackingTouch(SeekBar seekBar) { 
} 
@Override 
public void onStopTrackingTouch(SeekBar seekBar) { 
    seekBar.setSecondaryProgress(seekBar.getProgress()); 
} 



/*********************

/**Load seekbar's values from sharedpreferences*/ 
@Override

    super.onResume(); 

    loadedProgress1 = mPreferences.getInt(Key_PROGRESS_1, 50); 
    bar1.setProgress(loadedProgress1); 
    loadedProgress2 = mPreferences.getInt(Key_PROGRESS_2, 90); 
    bar2.setProgress(loadedProgress2); 
    loadedProgress3 = mPreferences.getInt(Key_PROGRESS_3, 70); 
    bar3.setProgress(loadedProgress3); 
}

    editor.putInt(Key_PROGRESS_1, savedProgress1); 
    savedProgress2 = bar2.getProgress(); 
    editor.putInt(Key_PROGRESS_2, savedProgress2); 
    savedProgress3 = bar3.getProgress(); 
    editor.putInt(Key_PROGRESS_3, savedProgress3); 
    editor.commit(); 
} 




/*********************

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    /**Inflate the menu; this adds items to the action bar if it is present.*/ 
    getMenuInflater().inflate(R.menu.menu_conf, menu); 
    return true; 
} 

/**Options menu where I call the send function*/ 
@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    switch (item.getItemId()) { 
     case R.id.send: 
      sendValues(); 
      break; 
     case R.id.reset: 
      resetValues(null); 
      break; 
    } 
    return true; 
} 




/*********************

public void sendValues() { 

    /**Seekbars values*/ 
    String message1 = progress1.getText().toString(); 
    String message2 = progress2.getText().toString(); 
    String message3 = progress3.getText().toString(); 

    /**Check that we're actually connected before trying anything*/ 
    if (GlobalVar.mTransmission.getState() != GlobalVar.STATE_CONNECTED) { 
     Toast.makeText(this, R.string.not_connected, Toast.LENGTH_SHORT).show(); 
     return; 
    } 

    /** 
    * 
    *HERE IS WHERE I'M TRYING TO CREATE A FUNCTION TO SEND THE 3 VALUES IN A STRING TYPE MESSAGE 
    *THIS CODE IS FROM THE SETUPCHAT() FUNCTION, SO IS WRONG IN THIS CASE   
    */ 

    /**Get the message bytes and tell the to write*/ 
    byte[] send = message.getBytes(); 
    GlobalVar.mTransmission.write(send); 

    /**Reset out string buffer to zero*/ 
    GlobalVar.mOutStringBuffer.setLength(0); 
} 


public void resetValues() { 

    defaultValue1 = 50; 
    bar1.setProgress(defaultValue1); 
    defaultValue2 = 90; 
    bar2.setProgress(defaultValue1); 
    defaultValue3 = 70; 
    bar3.setProgress(defaultValue1); 

} 

这是创建的新功能：

public void sendValues() { 

    /**Send the seekbars values*/ 
    String message = progress1.getText().toString()+":"+progress2.getText().toString()+":"+progress3.getText().toString(); 
    String[] values = message.split(":"); 
    for (String value : values) { 
     int number = Integer.valueOf(value); 
    } 

    /**Check that we're actually connected before trying anything*/ 
    if (GlobalVar.mTransmission.getState() != GlobalVar.STATE_CONNECTED) { 
     Toast.makeText(this, R.string.not_connected, Toast.LENGTH_SHORT).show(); 
     return; 
    } 

    /**Get the message bytes and tell the Transmission to write*/ 
    byte[] send = message.getBytes(); 
    GlobalVar.mTransmission.write(send); 

    /**Reset out string buffer to zero*/ 
    GlobalVar.mOutStringBuffer.setLength(0); 
} 

Answer 1

您可以将值作为一个正则表达式的前一个字符串。 "5:15:33"，然后在收到字符串":"时将其分开。像这样。

String str = bar1.getText().toString()+":"+bar2.getText().toString()+":"+bar3.getText().toString(); 

发送STR字符串到reciver和，那么你就可以得到INT的出字符串数组这样

String[] values = str.split(":"); 
    for (String value : values) { 
     int number = Integer.valueOf(value); 
    }
