Android编程入门-第3天

有了前两天的铺垫，今天对主函数进行编写，并实现相应功能：import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

public class QuizActivity extends Activity {

private Button mTrueButton;
private Button mFalseButton;

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

mTrueButton = (Button) findViewById(R.id.true_button);
mFalseButton = (Button) findViewById(R.id.false_button);

mTrueButton.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(QuizActivity.this, R.string.correct_toast, Toast.LENGTH_SHORT).show();
}
});
mFalseButton.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(QuizActivity.this, R.string.incorrect_toast, Toast.LENGTH_SHORT).show();
}
});
}
}
具体功能反应为，点击“True”按钮，弹出“Correct!”提示；点击“False”按钮，弹出“Incorrect!”提示。
