你可以通过使用字符串的分割功能使它变得更简单。



按照以下步骤操作：



1）用独特字符分隔大串时隙



2）将字符串传递给另一个活动



3）获取字符串并将其拆分为数组

第一项活动

 SQLiteDatabase db = openOrCreateDatabase（  MyDB，MODE_PRIVATE，null）; 
 Cursor c = db.rawQuery（  SELECT timeslots FROM medprofile，null）; 


字符串 timeslots =  跨度>; 
 int  i = 0; 
 while （c.moveToNext（））
 {
 String  uname = c.getString（c.getColumnIndex（  timeslots））; 
 timeslots + = uname +  ＃; 
 Toast.makeText（getApplicationContext（），uname，Toast.LENGTH_SHORT）.show（）; 
} 

意图=新意图（MainActivity。此，profileview。 class 跨度>）; 

 in.putExtra（  timeslots，timeslots）; 
 startActivity（in）; 

} 

第二项活动

在第二个活动的onCreate方法中添加此代码

 Bundle extras = getIntent（）。getExtras（） ; 
字符串 [] timeslots = extras.getString（  timeslots）。split（ ＃）; 

I want to get data from sqlite to an array and pass that array to next activity.i tried it as follow.but iam getting an error..please help me

SQLiteDatabase db = openOrCreateDatabase("MyDB",MODE_PRIVATE, null);
Cursor c=db.rawQuery("SELECT timeslots FROM medprofile",null);
	    
	    
String[] array = new String[c.getCount()];
int i=0;
while(c.moveToNext())
	{
		 String uname = c.getString(c.getColumnIndex("timeslots"));
			    array[i] = uname;
		  Toast.makeText(getApplicationContext(), array[i], Toast.LENGTH_SHORT).show();
		   i++;
	 }	
		 
	 Bundle b=new Bundle();
	b.putStringArray(null, new String[]{array[1], array[2]});

	Intent in=new Intent(MainActivity.this,profileview.class);
		
	 in.putExtras(b);
	 startActivity(in);
			
}

in next activity,i passed that array at the begining,

public class profileview extends ListActivity {
    Bundle b=this.getIntent().getExtras();
    String[] array=b.getStringArray(null);

but it doesnt work..i put null as a key.what is my mistake?

You can make it simpler by the use of string''s split function.

Follow these steps:

1)Make a large string of timeslots separated by unique character

2)Pass the string to another activity

3)Fetch the string and split it into array

First Activity

SQLiteDatabase db = openOrCreateDatabase("MyDB",MODE_PRIVATE, null);
Cursor c=db.rawQuery("SELECT timeslots FROM medprofile",null);
	    
	    
String timeslots="";
int i=0;
while(c.moveToNext())
	{
		 String uname = c.getString(c.getColumnIndex("timeslots"));
			    timeslots+=uname+"#";
		  Toast.makeText(getApplicationContext(), uname, Toast.LENGTH_SHORT).show();
	 }	
 
	Intent in=new Intent(MainActivity.this,profileview.class);
		
	 in.putExtra("timeslots",timeslots);
	 startActivity(in);
			
}

Second Activity

Add this code in onCreate method of second activity

 Bundle extras=getIntent().getExtras();
String[] timeslots=extras.getString("timeslots").split("#");
