如何使onClickListener for Android数组按钮工作

我创建了一个来自sqllite数据库的动态数组按钮。 对于我的生活，我无法设置点击监听器来单独处理每个按钮。 我一直在寻找3个小时但没有成功。

任何帮助，将不胜感激。 不要担心数据库废话，它只是听众。

imports... public class CreatePlayList extends Activity { ScrollView scrollleft, scrollright; LinearLayout songsright, songsleft; TextView testtext; String[][] allsongs; int numofsongs, i; Button b1[]; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.createplaylist); scrollleft = (ScrollView) findViewById(R.id.scrollleft); scrollright = (ScrollView) findViewById(R.id.scrollright); songsright = (LinearLayout) findViewById(R.id.layRight); songsleft = (LinearLayout) findViewById(R.id.layLeft); LyricDb connect = new LyricDb(CreatePlayList.this); connect.open(); numofsongs = connect.getNumSongs(); b1 = new Button[(numofsongs)]; allsongs = new String[numofsongs][2]; allsongs = connect.getSongArray(); connect.close(); testtext = new TextView(this); testtext.setText("Test"); songsleft.addView(testtext); for (i = 0; i < allsongs.length; i++) { b1[i] = new Button(this); b1[i].setText(allsongs[i][1]); songsright.addView(b1[i]); } b1[19].setText("test 123"); createClic(); } public void createClic(){ for (i = 0; i < (allsongs.length - 1); i++) { b1[i].setOnClickListener(new View.OnClickListener() { public void onClick(View v) { // TODO Auto-generated method stub testtext.setText(b1[i].getText()); } }); } } } 

Answer 1

转储在class级声明的’i’。 用这个替换方法（“按钮theButton”需要保持’最终’）。

 public void createClic() { for (int i = 0; i < (allsongs.length - 1); i++) { final Button theButton = b1[i]; theButton.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { // TODO Auto-generated method stub testtext.setText(theButton.getText()); } }); } } 

Answer 2

首先在Activity中实现OnClickListener，并在创建时将setOnClickListener（）方法调用到所有按钮。

 b[i].setOnClickListener(this); and also set id with each button b[i].setId(i); //and override this method @Override public void onClick(View v) { //here check which button called if(v.getId==1) { //its Button 1 do what ever u want } if(v.getId==2) { //its Button 2 do what ever u want its Button 2 } ...... } 

Answer 3

尝试一次……

 b1[i] = new Button[allsongs.length]; for (i = 0; i < allsongs.length; i++) { b1[i].setText(allsongs[i][1]); songsright.addView(b1[i]); }
