Question

hai是android中的新手我创建了一个动态按钮并编辑了文本创建我有两个页面1用于输入应该创建多少个按钮和编辑文本。（在该页面中我只有一个编辑文本字段和按钮，如果我输入3。三个edittext和3个按钮将在下一页动态创建）如果我按三个下一页将像三个按钮和三个edittext

我想在按输入ur1st time按钮的第一个编辑文本上打印你好，但是当我按下那个按钮时，值会打印在第三个edittext上代码如下：

package a.l;


   public class dyna extends Activity {
TextView t1;
Button btn;
EditText edt;
int i,j,t = 0,mHour,mMinute,count=0,mDate,mYear,mMonth;
Button b;
Toast mToast;
ScrollView sv;
Calendar c = Calendar.getInstance();
SQLiteDatabase myDB ; 
PendingIntent sender;
AlarmManager am;
Intent intent;
int alarmtype;
long timeinmilli;



protected static final int TIME_DIALOG_ID = 1;
 private static final int DATE_DIALOG_ID = 0;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.dyna);
t1 = (TextView)findViewById(R.id.textdyna);


 mHour = c.get(Calendar.HOUR_OF_DAY);
 mMinute = c.get(Calendar.MINUTE);
 mDate=c.get(Calendar.DATE);
 mMonth=c.get(Calendar.MONTH);
 mYear=c.get(Calendar.YEAR);
 String date=mDate+"/"+mMonth+"/"+mYear;
 count=1;



        Bundle bu =  getIntent().getExtras();
        String s1 = bu.getString("5");
        int i1=Integer.parseInt(s1);
        String s2 = bu.getString("3");
        String s3 = bu.getString("4");




//  if(date.equals(s2)){     
        sv = new ScrollView(this);
        LinearLayout ll = new LinearLayout(this);
        ll.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); 
        ll.setOrientation(LinearLayout.VERTICAL);
        ll.setBackgroundResource(R.drawable.vec);


        sv.addView(ll);

        for(i = 1; i <i1+1; i++)
        {
           b = new Button(this);

           b.setText(" enter ur"+ i +"st time");
           b.setId(i); 
           b.setTextSize(10);
           b.setPadding(8,3,8,3);   
           b.setTextColor(Color.DKGRAY);
           b.setTypeface(Typeface.SERIF, Typeface.BOLD_ITALIC);     
           b.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));        


           c.setTimeInMillis(System.currentTimeMillis());
            c.add(Calendar.SECOND,10);
            alarmtype=AlarmManager.RTC_WAKEUP;
            timeinmilli= c.getTimeInMillis();
           intent = new Intent(dyna.this, MyAlarmReceiver.class);
           sender = PendingIntent.getBroadcast(dyna.this,0, intent, 0);
           am = (AlarmManager)getSystemService(ALARM_SERVICE);



           edt=new EditText(this);
           edt.setId(i);
           edt.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));





           ll.addView(b);
           ll.addView(edt);
           System.out.println("am on");

           b.setOnClickListener(new View.OnClickListener() {

                @Override
                public void onClick(View v) {
                    int a=edt.getId();
                    int bh=b.getId();





                    //showDialog(TIME_DIALOG_ID);

                System.out.println("am on button");    

                        // We want the alarm to go off 10 seconds from now.


                      // c.add(Calendar.MINUTE,mMinute);


                        // Schedule the alarm!

   //                           am.set(alarmtype,timeinmilli, sender);
   //
  //                       
   //                           // Tell the user about what we did.
  //                            if (mToast != null) {
  //                                mToast.cancel();

   //       
                       }
            });



        }



        this.setContentView(sv);

Answer 2

为Button和EditText创建单独的数组...以便您可以轻松识别。另外，我可以看到您为Button和EditText设置了相同的ID。

在数组内部，只需初始化数组并在setOnClickListener的{{1}}内，设置相应的Button

在android中动态创建的edittext上设置文本？
