MIPS：如何在地址中存储数据？

Question

我需要知道如何选择某个地址来存储我的数据。

例如，正如您在图片中看到的，如何将4存储在0x20而不是0？

Answer 1

不使用pseudoinsctructions

public class BanglalinkInternetPack extends AppCompatActivity {

private SectionsPagerAdapter mSectionsPagerAdapter;

/**
 * The {@link ViewPager} that will host the section contents.
 */
private ViewPager mViewPager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_banglalink_internet_pack);
    //getSupportActionBar().setBackgroundDrawable(new ColorDrawable(Color.parseColor("#f37022")));

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    // Create the adapter that will return a fragment for each of the three
    // primary sections of the activity.
    mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());

    // Set up the ViewPager with the sections adapter.
    mViewPager = (ViewPager) findViewById(R.id.container);
    mViewPager.setAdapter(mSectionsPagerAdapter);

    TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
    tabLayout.setupWithViewPager(mViewPager);

    FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                    .setAction("Action", null).show();
        }
    });

}


/**
 * A {@link FragmentPagerAdapter} that returns a fragment corresponding to
 * one of the sections/tabs/pages.
 */
public class SectionsPagerAdapter extends FragmentPagerAdapter {

    public SectionsPagerAdapter(FragmentManager fm) {
        super(fm);
    }

    @Override
    public Fragment getItem(int position) {
        // getItem is called to instantiate the fragment for the given page.
        // Return a PlaceholderFragment (defined as a static inner class below).
        switch (position){
            case 0:
                return new Montly_pack_bl();

            case 1:
                return  new Daily_packs_bl();

            case 2:
                return  new Weekly_pack_bl();

            case 3:
                return  new Montly_pack_bl();

        }
        return null;
    }

    @Override
    public int getCount() {
        // Show 4 total pages.
        return 4;
    }

    @Override
    public CharSequence getPageTitle(int position) {
        switch (position) {
            case 0:
                return "Most Used";
            case 1:
                return "Daily";
            case 2:
                return "Weekly";
            case 3:
                return "Monthly";
        }
        return null;
    }

}
