嘿,今天的你过的还好吗,今天分享自己的BaseActivity内容,仅供参考

调用也很容易
public class MainActivity extends BaseActivity {

//设置是否显示标题栏
setShowTitle(true);
//设置是否显示状态栏
setShowStatusBar(true);
//是否允许屏幕旋转
setAllowScreenRoate(true);
//以上设置一定要在 super.onCreate(savedInstanceState) 方法之前设置
super.onCreate(savedInstanceState);
}
@Override
protected int initLayout() {
//初始化布局
return R.layout.activity_main;
}
@Override
protected void initView() {
//初始化控件
Button button = new Button(context);
button.setText("click");
//每秒只响应一次点击事件
button.setOnClickListener(new OnSingleClickListener() {
@Override
public void onSingleClick(View view) {
}
});
//每秒可以重复响应点击事件
button.setOnClickListener(new OnMultiClickListener() {
@Override
public void onMultiClick(View view) {
}
});
}
@Override
protected void initData() {
//初始化、绑定数据
}
}
