slpash屏幕后主要活动获得白屏

标签： java android xml splash-screen

我正在创建一个应用，其中我在一个项目中创建了导航抽屉，并在启动画面和一个随机活动 >第二个项目。 所以我试图合并他们。我设置了启动画面和随机活动，因此合并已正确完成。

然后我在随机活动上设置按钮，重定向到主要活动（此处为homeActivity）但是当我点击按钮时，它会获得白屏。

在homeAcitivity中我有使用导航抽屉作为我已经提到所以如何解决mainActivity上的白屏问题??? 我在这里看到了一些问题，但我没有得到我的解决方案......

使用android studion 2.1.2 gradle版本2.10

由于

CODE

这里是mainActivity（这里是homeActivity）

public class homeActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
ListView list;
String[] menutitles;
String[] menudescriptions;
int images[]={R.drawable.mouse, R.drawable.keyboard, R.drawable.filemanager, R.drawable.media, R.drawable.power};

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    Resources res = getResources();
    menutitles=res.getStringArray(R.array.titles);
    menudescriptions=res.getStringArray(R.array.descriptions);
    list = (ListView) findViewById(R.id.listView);
    listadapter adptr=new listadapter(this,menutitles,images,menudescriptions);
    list.setAdapter(adptr);
    onclick();
    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
            this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
    drawer.setDrawerListener(toggle);
    toggle.syncState();

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);
}
 public void onBackPressed() {
        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        if (drawer.isDrawerOpen(GravityCompat.START)) {
            drawer.closeDrawer(GravityCompat.START);
        } else {
            super.onBackPressed();
        }
    }

   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 boolean onNavigationItemSelected(MenuItem item) {
    // Handle navigation view item clicks here.
    int id = item.getItemId();

    if (id == R.id.nav_mouse) {
        Intent intentu = new Intent("com.example.admin.pcremote.MouseActivity");
        startActivity(intentu);
    } else if (id == R.id.nav_keyboard) {
        Intent intentu = new Intent("com.example.admin.pcremote.KeyboardActivity");
        startActivity(intentu);
    } else if (id == R.id.nav_filemanager) {
        Intent intentu = new Intent("com.example.admin.pcremote.FilemanagerActivity");
        startActivity(intentu);
    } else if (id == R.id.nav_media) {
        Intent intentu = new Intent("com.example.admin.pcremote.MediaActivity");
        startActivity(intentu);
    } else if (id == R.id.nav_power) {
        Intent intentu = new Intent("com.example.admin.pcremote.PowerActivity");
        startActivity(intentu);
    }else if (id == R.id.nav_send) {
        AlertDialog.Builder builder = new AlertDialog.Builder(homeActivity.this);
        builder.setMessage("Do You Want To Exit?").setCancelable(false)
                .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        finish();
                    }
                }).setNegativeButton("No", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.cancel();
            }
        });
        AlertDialog alert = builder.create();
        alert.setTitle("Exit!!");
        alert.show();
    }

   DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    drawer.closeDrawer(GravityCompat.START);
    return true;
}
