編輯:關於Android編程
一直想做游戲,先拿一個簡單點的學習,寫的代碼分享出來,大神可以指點~
直接上代碼:
import android.app.Activity; import android.os.Bundle; import android.view.Menu; import android.widget.TextView; public class MainActivity extends Activity { public MainActivity() { mainActivity = this; } @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); tvScore = (TextView) findViewById(R.id.tvScore); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } public void clearScore(){ score = 0; showScore(); } public void showScore(){ tvScore.setText(score+""); } public void addScore(int s){ score+=s; showScore(); } private int score = 0; private TextView tvScore; private static MainActivity mainActivity = null; public static MainActivity getMainActivity() { return mainActivity; } }

Android高手進階——Adapter深入理解與優化 一般是針對包含多個元素的View,如ListView,GridView,ExpandableList
效果圖點擊標簽,指示線滑動到當前的標簽下。 用到的技術: activity中添加 fragement, ViewPager, 自定義繪制view-Activity中動態添
-- RecyclerView簡單入門一、加入JAR包第一感覺這個東東,好復雜,沒ListView來的快,方便在項目中加入android-support-v7-recyc
android中的json的讀取1.讀取Json文件中的json內容首先在將json文件放在目錄assets下:test.json {programmers:[
