android 批量插入数据

1. 使用ContentValues插入

db.beginTransaction(); // 手动设置开始事务
for (ContentValues v : list) {
db.insert("bus_line_station", null, v);
}
db.setTransactionSuccessful(); // 设置事务处理成功，不设置会自动回滚不提交
db.endTransaction(); // 处理完成

db.close();

public void inertOrUpdateDateBatch(List<String> sqls) {
SQLiteDatabase db = getWritableDatabase();
db.beginTransaction();
try {
for (String sql : sqls) {
db.execSQL(sql);
}
// 设置事务标志为成功，当结束事务时就会提交事务
db.setTransactionSuccessful();
}catch (Exception e) {
e.printStackTrace();
}finally {
// 结束事务
db.endTransaction();
db.close();
}  

}

3. 使用InsertHelper类

InsertHelper ih = new InsertHelper(db, "bus_line_station");
db.beginTransaction();
final int directColumnIndex = ih.getColumnIndex("direct");
final int lineNameColumnIndex = ih.getColumnIndex("line_name");
final int snoColumnIndex = ih.getColumnIndex("sno");
final int stationNameColumnIndex = ih.getColumnIndex("station_name");
try {
for (Station s : busLines) {
ih.prepareForInsert();
ih.bind(directColumnIndex, s.direct);
ih.bind(lineNameColumnIndex, s.lineName);
ih.bind(snoColumnIndex, s.sno);
ih.bind(stationNameColumnIndex, s.stationName);
ih.execute();
}
db.setTransactionSuccessful();
}finally {
ih.close();
db.endTransaction();
db.close();
}

String sql = "insert into bus_line_station(direct,line_name,sno,station_name) values(?,?,?,?)";
SQLiteStatement stat = db.compileStatement(sql);
db.beginTransaction();
for (Station line : busLines) {
stat.bindLong(1, line.direct);
stat.bindString(2, line.lineName);
stat.bindLong(3, line.sno);
stat.bindString(4, line.stationName);
stat.executeInsert();
}
db.setTransactionSuccessful();
db.endTransaction();
db.close();
