java提示 method buttonPressed未调用

Question

package com.example.myapplicationforexample;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

import android.util.Log;

import android.view.View;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {
TextView mTextView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setupUI();
}

private void setupUI(){
    setContentView(R.layout.activity_main);
    mTextView = (TextView) findViewById(R.id.textView);
}

// Create a local variable for identifying the class where the log statements come from.
private final static String LOG_TAG = MainActivity.class.getSimpleName();

public void buttonPressed(View view){
    Log.i(LOG_TAG, "buttonPressed(View) Called");

    String stringValue = "Hello World!";

    mTextView.setText(stringValue);

    Log.v(LOG_TAG, " text changed to:" + stringValue);

    Log.d(LOG_TAG, "buttonPressed(View) finished");
}

}

rt, 我在安卓机上按按钮，Android studio的logcat没有反应，是否是这段代码的问题呢，求助，谢谢各位大腿~

buttonPressed按钮事件没有调用？看看有没有注册按钮事件，http://www.cnblogs.com/guwei4037/p/5639462.html
