//采用android sharedpreferences 进行数据的保存读取SharedPreferences sharedPreferences;private final String mediaShare = "test";private void InitMediaSharePreference() {    sharedPreferences = this.getSharedPreferences(mediaShare, MODE_PRIVATE);}//写入String mdatStr = String.format("data_%d%d.yourdata", name1, name2);SharedPreferences.Editor editor = sharedPreferences.edit();editor.putInt(mdatStr, startMdatPlace);editor.putString("STRING_KEY", "string");editor.putBoolean("BOOLEAN_KEY", true);editor.commit();//查找int startMdatPlace = sharedPreferences.getInt(String.format("data_%d%d.yourdata", name1, name2), -1);if (startMdatPlace != -1) {    //如果文件不存在}else{    //找到文件，读取}
