本文实例为大家分享了SharedPreferences简单使用案例，供大家参考，具体内容如下

MainActivity：

public class SharedPreferencesTestActivity extends Activity implements View.OnClickListener{ private EditText editText; private TextView textView; private Button write; private Button read; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_shared_preferences_test); initView(); write.setOnClickListener(this); read.setOnClickListener(this); } private void initView() { editText=(EditText)findViewById(R.id.Edit_Test); textView=(TextView)findViewById(R.id.Text_Test); write=(Button)findViewById(R.id.write); read=(Button)findViewById(R.id.read); } @Override public void onClick(View v) { switch (v.getId()){ case R.id.write: String some=editText.getText().toString(); SharedPreferences pref = SharedPreferencesTestActivity.this.getSharedPreferences("data",MODE_PRIVATE); SharedPreferences.Editor editor = pref.edit(); editor.putString("Content",some); editor.commit(); Toast.makeText(SharedPreferencesTestActivity.this, "写入成功" , Toast.LENGTH_LONG).show(); editText.setText(""); break; case R.id.read: SharedPreferences pre = getSharedPreferences("data",MODE_PRIVATE); String name = pre.getString("Content",""); textView.setText(name); Toast.makeText(SharedPreferencesTestActivity.this, "读取成功" , Toast.LENGTH_LONG).show(); break; } }}

MainActivity.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" tools:context="com.fae.mobile.testActivity.SharedPreferencesTestActivity"> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal"> <EditText android:textColor="@color/red" android:background="@null" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/Edit_Test" android:layout_weight="1" /> <TextView android:textColor="@color/blue" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/Text_Test" android:layout_weight="1"/> </LinearLayout> <Button android:layout_marginTop="25dp" android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/read" android:text="读"/> <Button android:layout_marginTop="25dp" android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/write" android:text="写"/></LinearLayout>
