I have a Tab Bar with 5 items 4 of these opens a new fragment while 1 of them should open a new activity, I can't figure out how to open this new activity.
I need the 3rd item to open a new activity(case 2).
I appreciate any help in this issue. Thank you.
Here is my MainActivity :
public class MainActivity extends AppCompatActivity {
private SectionsPagerAdapter mSectionsPagerAdapter;
private ViewPager mViewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);
toolbar.setTitle("");
toolbar.setSubtitle("");
// 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);
mViewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.addOnTabSelectedListener(new TabLayout.ViewPagerOnTabSelectedListener(mViewPager));
}
public static class PlaceholderFragment extends Fragment {
private static final String ARG_SECTION_NUMBER = "section_number";
public PlaceholderFragment() {
}
public static PlaceholderFragment newInstance(int sectionNumber) {
PlaceholderFragment fragment = new PlaceholderFragment();
Bundle args = new Bundle();
args.putInt(ARG_SECTION_NUMBER, sectionNumber);
fragment.setArguments(args);
return fragment;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main, container, false);
TextView textView = (TextView) rootView.findViewById(R.id.section_label);
textView.setText(getString(R.string.section_format, getArguments().getInt(ARG_SECTION_NUMBER)));
return rootView;
}
}
public class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
Fragment fragment = null;
switch (position){
case 0:
fragment = new Frag1();
break;
case 1:
fragment = new Frag2();
break;
case 2:
fragment = new Frag3();
break;
case 3:
fragment = new Frag4();
break;
case 4:
fragment = new Frag5();
break;
}
return fragment;
}
@Override
public int getCount() {
// Show 5 total pages.
return 5;
}
}
public static Bitmap TrimBitmap(Bitmap bmp) {
int imgHeight = bmp.getHeight();
int imgWidth = bmp.getWidth();
//TRIM WIDTH - LEFT
int startWidth = 0;
for(int x = 0; x < imgWidth; x++) {
if (startWidth == 0) {
for (int y = 0; y < imgHeight; y++) {
if (bmp.getPixel(x, y) != Color.TRANSPARENT) {
startWidth = x;
break;
}
}
} else break;
}
//TRIM WIDTH - RIGHT
int endWidth = 0;
for(int x = imgWidth - 1; x >= 0; x--) {
if (endWidth == 0) {
for (int y = 0; y < imgHeight; y++) {
if (bmp.getPixel(x, y) != Color.TRANSPARENT) {
endWidth = x;
break;
}
}
} else break;
}
//TRIM HEIGHT - TOP
int startHeight = 0;
for(int y = 0; y < imgHeight; y++) {
if (startHeight == 0) {
for (int x = 0; x < imgWidth; x++) {
if (bmp.getPixel(x, y) != Color.TRANSPARENT) {
startHeight = y;
break;
}
}
} else break;
}
//TRIM HEIGHT - BOTTOM
int endHeight = 0;
for(int y = imgHeight - 1; y >= 0; y--) {
if (endHeight == 0 ) {
for (int x = 0; x < imgWidth; x++) {
if (bmp.getPixel(x, y) != Color.TRANSPARENT) {
endHeight = y;
break;
}
}
} else break;
}
return Bitmap.createBitmap(
bmp,
startWidth,
startHeight,
endWidth - startWidth,
endHeight - startHeight
);
}
}
xml for tabbar(not sure if needed):
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabBackground="@color/colorPrimaryDark"
app:tabGravity="fill"
app:tabIndicatorColor="@color/colorAccent"
app:tabMode="fixed"
app:tabSelectedTextColor="@android:color/background_light"
app:tabTextAppearance="@style/TabLayoutStyle"
app:tabTextColor="@android:color/background_light"
>
<android.support.design.widget.TabItem
android:id="@+id/tabItem"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="1" />
<android.support.design.widget.TabItem
android:id="@+id/tabItem2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="2" />
<android.support.design.widget.TabItem
android:id="@+id/tabItem3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="3" />
<android.support.design.widget.TabItem
android:id="@+id/tabItem4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="4" />
<android.support.design.widget.TabItem
android:id="@+id/tabItem5"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="5" />
</android.support.design.widget.TabLayout>
Use your own OnTabSelectedListener
:
tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
void onTabSelected(TabLayout.Tab tab) {
if (tab.getPosition() == 2) { // 3rd item selected
// Open your activity here
}
}
void onTabUnselected(TabLayout.Tab tab) {}
void onTabReselected(TabLayout.Tab tab) {}
});
check for the tab item which you want(I am assuming you want to open the activity on case 2
if I am right, if not please change the code accordingly):
@Override
public Fragment getItem(int position) {
Fragment fragment = null;
switch (position){
case 0:
fragment = new Frag1();
break;
case 1:
fragment = new Frag2();
break;
case 2:
//open new activity
startActivity(new Intent(CurrentClassName.this, OtherClassName.class));
break;
case 3:
fragment = new Frag4();
break;
case 4:
fragment = new Frag5();
break;
}
return fragment;
}
Please be sure to change the CurrentClassName
to what is the TabLayout activity's class name and OtherClassName
to the class which you want to open!
