这是我的代码：

@Override
protected void onCreate(Bundle icicle) {
    super.onCreate(icicle);

    setContentView(R.layout.translate_activity);
    mFromEditText = (EditText) findViewById(R.id.input);
    mToEditText = (EditText) findViewById(R.id.translation);
    mFromButton = (Button) findViewById(R.id.from);
    mToButton = (Button) findViewById(R.id.to);
    mTranslateButton = (Button) findViewById(R.id.button_translate);
    mSwapButton = (Button) findViewById(R.id.button_swap);
    mProgressBar = (ProgressBar) findViewById(R.id.progress_bar);
    mStatusView = (TextView) findViewById(R.id.status);

    //
    // Install the language adapters on both the From and To spinners.
    //
    //****************this is line 132 from the error log************************************//
    mFromButton.setOnClickListener(mClickListener);
    mToButton.setOnClickListener(mClickListener);

    mTranslateButton.setOnClickListener(this);
    mSwapButton.setOnClickListener(this);
    mFromEditText.selectAll();

    connectToTranslateService();
}
