Android简单数据存储类SharedPreferences详解及实例

核心提示：sp.edit().putString("account",etAccount.getText().toString()).commit();sp.edit().putString("password",etPW.getText().toString()).commit();}}

sp.edit().putString("account",

etAccount.getText().toString()).commit();

sp.edit().putString("password",

etPW.getText().toString()).commit();

}

}

}

});

btnExit.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

System.exit(0);

}

});

tvClear.setOnClickListener(new OnClickListener(){

@Override

public void onClick(View v) {sp=getSharedPreferences("UserInfo", 0);

sp.edit().clear().commit();

}});

}

//初始化配置

private void InitConfig() {

sp = getSharedPreferences("UserInfo", 0);

etAccount.setText(sp.getString("account", null));

etPW.setText(sp.getString("password", null));

cbal.setChecked(sp.getBoolean("cbal", false));

cbrp.setChecked(sp.getBoolean("cbrp", false));

}

}

说明：

1.写内容

sp = getSharedPreferences("UserInfo", 0);

sp.edit().putBoolean("cbal", isChecked).commit();

UserInfo是指xml文件的文件名，如果此文件已存在则直接向其中写内容“isChecked”的值，首先通过SharedPreferences的edit()方法创建editor,然后调用commit()方法提修改

2.读内容

sp = getSharedPreferences("UserInfo", 0);

etAccount.setText(sp.getString("account", null));

etPW.setText(sp.getString("password", null));

cbal.setChecked(sp.getBoolean("cbal", false));

cbrp.setChecked(sp.getBoolean("cbrp", false));
