4，求一个android小程序代码 在文本框1和文本框2输入一个数字文本框文本框1 ， 2,3以下简写为et1，et2，et3初始化的代码就不写了，按你的layout里的id为准 。之后的代码这么写：et1.addTextChangedListener(watcher);et2.addTextChangedListener(watcher);private TextWatcher watcher = new TextWatcher()@Overridepublic void onTextChanged(CharSequence s, int start, int before, int count)// TODO Auto-generated method stub}@Overridepublic void beforeTextChanged(CharSequence s, int start, int count,int after)// TODO Auto-generated method stub}@Overridepublic void afterTextChanged(Editable s)// TODO Auto-generated method stubint a = Integer.parseInt(et1.getText().toString);//实际上要捕获异常，这里就偷个懒int b = Integer.parseInt(et2.getText().toString);//同上int sum = a+b;String text = sum+"";et3.setText(text .subString(text.length()-1,text.length());}};5，初学Android开发求一个完整的详细的Android小程序源码参考媒体播放器源码Audio.javapackage org.example.audio;import android.app.Activity;import android.media.MediaPlayer;import android.os.Bundle;import android.view.KeyEvent;public class Audio extends Activity {private MediaPlayer up, down, left, right, enter;private MediaPlayer a, s, d, f;@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);// Native rate is 44.1kHz 16 bit stereo, but// to save space we just use MPEG-3 22kHz monoup = MediaPlayer.create(this, R.raw.up);down = MediaPlayer.create(this, R.raw.down);left = MediaPlayer.create(this, R.raw.left);right = MediaPlayer.create(this, R.raw.right);enter = MediaPlayer.create(this, R.raw.enter);a = MediaPlayer.create(this, R.raw.a);s = MediaPlayer.create(this, R.raw.s);d = MediaPlayer.create(this, R.raw.d);f = MediaPlayer.create(this, R.raw.f);}@Overridepublic boolean onKeyDown(int keyCode, KeyEvent event) {MediaPlayer mp;switch (keyCode) {case KeyEvent.KEYCODE_DPAD_UP:mp = up;break;case KeyEvent.KEYCODE_DPAD_DOWN:mp = down;break;case KeyEvent.KEYCODE_DPAD_LEFT:mp = left;break;case KeyEvent.KEYCODE_DPAD_RIGHT:mp = right;break;case KeyEvent.KEYCODE_DPAD_CENTER:case KeyEvent.KEYCODE_ENTER:mp = enter;break;case KeyEvent.KEYCODE_A:mp = a;break;case KeyEvent.KEYCODE_S:mp = s;break;case KeyEvent.KEYCODE_D:mp = d;break;case KeyEvent.KEYCODE_F:mp = f;break;default:return super.onKeyDown(keyCode, event);}mp.seekTo(0);mp.start();return true;}}
