不使用ViewPager的TabLayout [英] TabLayout without using ViewPager
问题描述
我想实现TabLayout
,因为它很简单,但是我发现的所有教程都涉及到ViewPager
.我只想要类似OnClickListener
的东西,如果单击Add
图标,它将显示一个显示选项卡1"的祝酒词,如果单击日历图标,它将显示一个显示选项卡2"的祝酒词>
我想使用TabLayout
,因为它可以处理设备旋转.
Main_activity.java
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
// Add five tabs. Three have icons and two have text titles
tabLayout.addTab(tabLayout.newTab().setIcon(R.drawable.add_live));
tabLayout.addTab(tabLayout.newTab().setIcon(R.drawable.calendar_live));
tabLayout.addTab(tabLayout.newTab().setIcon(R.drawable.group_live));
tabLayout.addTab(tabLayout.newTab().setText("Send"));
tabLayout.addTab(tabLayout.newTab().setText("Send & Post"));
}
}
activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:app="http://schemas.android.com/tools">
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="fixed"
app:tabGravity="fill" />
</RelativeLayout>
我发现 setOnTabSelectedListener
:
tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
@Override
public void onTabSelected(TabLayout.Tab tab) {
if(tabLayout.getSelectedTabPosition() == 0){
Toast.makeText(MainActivity.this, "Tab " + tabLayout.getSelectedTabPosition(), Toast.LENGTH_LONG).show();
}else if(tabLayout.getSelectedTabPosition() == 1){
Toast.makeText(MainActivity.this, "Tab " + tabLayout.getSelectedTabPosition(), Toast.LENGTH_LONG).show();
}else if(tabLayout.getSelectedTabPosition() == 2){
Toast.makeText(MainActivity.this, "Tab " + tabLayout.getSelectedTabPosition(), Toast.LENGTH_LONG).show();
}else if(tabLayout.getSelectedTabPosition() == 3){
Toast.makeText(MainActivity.this, "Tab " + tabLayout.getSelectedTabPosition(), Toast.LENGTH_LONG).show();
}else if(tabLayout.getSelectedTabPosition() == 4){
Toast.makeText(MainActivity.this, "Tab " + tabLayout.getSelectedTabPosition(), Toast.LENGTH_LONG).show();
}
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
}
I want to implement a TabLayout
because it is simple but all the tutorials I have found involve a ViewPager
. I just want something like OnClickListener
where if I click the Add
icon, it will show a toast that displays "tab 1" and if I click a calendar icon, it will show a toast that displays "tab 2"
I would like to use TabLayout
because it handles device rotations.
Main_activity.java
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
// Add five tabs. Three have icons and two have text titles
tabLayout.addTab(tabLayout.newTab().setIcon(R.drawable.add_live));
tabLayout.addTab(tabLayout.newTab().setIcon(R.drawable.calendar_live));
tabLayout.addTab(tabLayout.newTab().setIcon(R.drawable.group_live));
tabLayout.addTab(tabLayout.newTab().setText("Send"));
tabLayout.addTab(tabLayout.newTab().setText("Send & Post"));
}
}
activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:app="http://schemas.android.com/tools">
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="fixed"
app:tabGravity="fill" />
</RelativeLayout>
I found setOnTabSelectedListener
:
tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
@Override
public void onTabSelected(TabLayout.Tab tab) {
if(tabLayout.getSelectedTabPosition() == 0){
Toast.makeText(MainActivity.this, "Tab " + tabLayout.getSelectedTabPosition(), Toast.LENGTH_LONG).show();
}else if(tabLayout.getSelectedTabPosition() == 1){
Toast.makeText(MainActivity.this, "Tab " + tabLayout.getSelectedTabPosition(), Toast.LENGTH_LONG).show();
}else if(tabLayout.getSelectedTabPosition() == 2){
Toast.makeText(MainActivity.this, "Tab " + tabLayout.getSelectedTabPosition(), Toast.LENGTH_LONG).show();
}else if(tabLayout.getSelectedTabPosition() == 3){
Toast.makeText(MainActivity.this, "Tab " + tabLayout.getSelectedTabPosition(), Toast.LENGTH_LONG).show();
}else if(tabLayout.getSelectedTabPosition() == 4){
Toast.makeText(MainActivity.this, "Tab " + tabLayout.getSelectedTabPosition(), Toast.LENGTH_LONG).show();
}
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
}
