一段代码 完全解读 SharedPreferedces。

InputStream open = getAssets().open("word/wrods.txt");
InputStreamReader reader = new InputStreamReader(open);
BufferedReader Buffer = new BufferedReader(reader);
String black = "";
String line = "";
while ((line = Buffer.readLine()) != null) {
black += line.trim();
}
JSONObject object = new JSONObject(black);

SharedPreferences sharedPref = getSharedPreferences("Black", Context.MODE_PRIVATE);
SharedPreferences.Editor edit = sharedPref.edit();
edit.putString("black", black);
edit.commit();

SharedPreferences preferences = getSharedPreferences("Black", Context.MODE_PRIVATE);
String black = preferences.getString("black", "没有获取到敏感词");
System.out.println("=======TAG=black==========" + black);
