Good Day!私は現在アンドロイドアプリを作成中です。私の最初の問題は、私のTabLayoutに問題があります。ツールバーでTabLayoutを使用するには?
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Create the adapter that will return a fragment for each section
mPagerAdapter = new FragmentPagerAdapter(getSupportFragmentManager()) {
private final Fragment[] mFragments = new Fragment[] {
new MyPostsFragment(),
new MyPostsFragment(),
new MyPostsFragment(),
};
private final String[] mFragmentNames = new String[] {
getString(R.string.heading_recent),
getString(R.string.heading_recent),
getString(R.string.heading_recent)
};
@Override
public Fragment getItem(int position) {
return mFragments[position];
}
@Override
public int getCount() {
return mFragments.length;
}
@Override
public CharSequence getPageTitle(int position) {
return mFragmentNames[position];
}
};
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mPagerAdapter);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(mViewPager);
// Button launches NewPostActivity
findViewById(R.id.fab_new_post).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
startActivity(new Intent(MainActivity.this, NewReportActivity.class));
}
});
}
そして、これはレイアウトです::
あなたが単に非表示にすることができます<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
