1.多个Activity共用相同布局或者相同控件:避免重复代码
BaseActivit代码:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 | public class BaseActivity extends Activity implements OnClickListener { /* * 多个Activity共用相同布局或者相同控件 * 写个基类继承,避免重复代码 */ @Override public void onClick(View v) { switch (v.getId()) { case R.id.common_titlebar_btn_back: finish(); break ; default : break ; } baseOnClick(v); } protected void baseOnClick(View v) { } @Override protected void onCreate(Bundle savedInstanceState) { super .onCreate(savedInstanceState); // setContentView(R.layout.activity_base); } @Override protected void onResume() { super .onResume(); onPostOnCreate(); } public final void onPostOnCreate() //find同一个控件 { findViewById(R.id.common_titlebar_btn_back).setOnClickListener( this ); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.base, menu); return true ; } } |
子类代码:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | public class ThirdActivity extends BaseActivity { /** * layout里复用同一布局: * <include * android:id="@+id/include1" * layout="@layout/common_titlebar" /> */ @Override protected void onCreate(Bundle savedInstanceState) { super .onCreate(savedInstanceState); setContentView(R.layout.activity_third_main); } } |
