可以帮我写一个功能齐全的android的baseActivity抽象类

当然可以，以下是一个功能齐全的android的baseActivity抽象类的代码：

public abstract class BaseActivity extends AppCompatActivity {

    private ProgressDialog mProgressDialog;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(getLayoutId());
        initView();
        initData();
    }

    protected abstract int getLayoutId();

    protected abstract void initView();

    protected abstract void initData();

    protected void showProgressDialog(String message) {
        if (mProgressDialog == null) {
            mProgressDialog = new ProgressDialog(this);
            mProgressDialog.setCancelable(false);
        }
        mProgressDialog.setMessage(message);
        mProgressDialog.show();
    }

    protected void hideProgressDialog() {
        if (mProgressDialog != null && mProgressDialog.isShowing()) {
            mProgressDialog.dismiss();
        }
    }

    protected void showToast(String message) {
        Toast.makeText(this, message, Toast.LENGTH_SHORT).show();
    }

    protected void startActivity(Class<?> cls) {
        startActivity(new Intent(this, cls));
    }

    protected void startActivity(Class<?> cls, Bundle bundle) {
        Intent intent = new Intent(this, cls);
        intent.putExtras(bundle);
        startActivity(intent);
    }

    protected void startActivityForResult(Class<?> cls, int requestCode) {
        startActivityForResult(new Intent(this, cls), requestCode);
    }

    protected void startActivityForResult(Class<?> cls, int requestCode, Bundle bundle) {
        Intent intent = new Intent(this, cls);
        intent.putExtras(bundle);
        startActivityForResult(intent, requestCode);
    }
}

这个抽象类包含了常用的一些方法，比如显示进度对话框、隐藏进度对话框、显示Toast、启动Activity等等。你可以根据自己的需要进行修改和扩展。
