我正在开发一个基于 BluetoothChat 示例的应用程序，其中我有 2 个按钮的主要活动：

1. Find devices
2. Configuration

使用第一个按钮，我搜索具有与上述示例相同的代码的设备。

使用第二个按钮，我进入另一个活动，其中有 3 个搜索栏，每个搜索栏下都有文本视图，显示当前搜索栏的值。

我需要修改 BluetoothChat 示例的代码以发送包含这 3 个值而不是文本的数组。

这是我正在尝试开发的此活动的代码。

我怎样才能做到这一点？

    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*/

@Override

@Override

    seekBar.setSecondaryProgress(seekBar.getProgress());
}



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

@Override

    super.onResume();

    loadedProgress1 = mPreferences.getInt(Key_PROGRESS_1, 50);
    bar1.setProgress(loadedProgress1);
    loadedProgress2 = mPreferences.getInt(Key_PROGRESS_2, 90);
    bar2.setProgress(loadedProgress2);

    savedProgress3 = bar3.getProgress();
    editor.putInt(Key_PROGRESS_3, savedProgress3);
    editor.commit();
}

}

    switch (item.getItemId()) {
        case R.id.send:
            sendValues();

        case R.id.reset:
            resetValues(null);
            break;
    }
    return true;

    /**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 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);

}

这是创建的新函数：

    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);
}

您可以使用正则表达式 ex 将值作为字符串发送。"5:15:33"然后在收到这样的字符串时将其拆分":"。

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

将 str String 发送到接收器，然后您可以像这样从 String 数组中获取 int

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