问题
I am new to android. I am creating an app which consists of a view pager with a swipe tab layout. When I click the button it does some calculations inside of the view pager. While it's doing this I want the switching between the tabs to be disabled. So no swiping between the pages while it's calculating. After the calculations are completed I want the switching to be enabled again. Can anyone tell me how to do this please? Thanks in advance. I tried this. Please have a look at it:
public class Auto extends FragmentActivity{
Button tests;
private ViewPager pager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.auto);
tests = (PaperButton)findViewById(R.id.action_button_tests);
tests.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if(pager.getCurrentItem()==0){
tests.setTag(1);
tests.setText("START TEST");
final int status = (Integer)v.getTag();
if(status==1){
tests.setText("STOP TEST");
v.setTag(0);
int i;
Login.Communication_Ok=false;
for( i=0;(i<5 && Login.Communication_Ok!=true);i++)
Login.Send_Commands_To_Micro_Controller(1);
if(Login.Communication_Ok==true)
{
Video_Status=false;
Login.Bucket_Status = false;
Login.Auto_Mode_Bfr_Fuse =false;
for( i=0;(i<5 && Login.Auto_Mode_Bfr_Fuse!=true);i++)
Login.Send_Commands_To_Micro_Controller(3);
if(Login.Auto_Mode_Bfr_Fuse==true)
Toast.makeText(Auto.this, "Test started", Toast.LENGTH_LONG).show();
else
{
Toast.makeText(Auto.this, "Communication Failure in Before Fuse connection Segment", Toast.LENGTH_LONG).show();
tests.setText("START TEST");
v.setTag(1);
return;
}
Test_Completed=false;
if(!Auto_Bucket_Tests_Thread.isAlive())
Auto_Bucket_Tests_Thread.start();
}
}
else{
tests.setText("START TEST");
v.setTag(1);
}
}
if(pager.getCurrentItem()==1){
tests.setTag(1);
tests.setText("START TEST");
final int status = (Integer)v.getTag();
if(status==1){
tests.setText("STOP TEST");
v.setTag(0);
int i;
Login.Communication_Ok=false;
for( i=0;(i<5 && Login.Communication_Ok!=true);i++)
Login.Send_Commands_To_Micro_Controller(1);
if(Login.Communication_Ok==true)
{
Video_Status=false;
Login.Bucket_Status = false;
Login.Automode_After_connecting_fuse =false;
for( i=0;(i<5 && Login.Automode_After_connecting_fuse!=true);i++)
Login.Send_Commands_To_Micro_Controller(4);
if(Login.Automode_After_connecting_fuse==true){
Toast.makeText(Auto.this, "Test started", Toast.LENGTH_LONG).show();
**/*For Disabling swipe between tabs*/**
pager.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
pager.getCurrentItem();
return false;
}
});
pager.setEnabled(false);
}
else
{
Toast.makeText(Auto.this, "Communication Failure in After Fuse connection Segment", Toast.LENGTH_LONG).show();
tests.setText("START TEST");
v.setTag(1);
return;
}
Test_Completed=false;
}
}
else{
tests.setText("START TEST");
v.setTag(1);
}
}
} }

public class CustomViewPager extends ViewPager {
private boolean enabled;
public CustomViewPager(Context context, AttributeSet attrs) {
super(context, attrs);
this.enabled = true;
}
@Override
public boolean onTouchEvent(MotionEvent event) {
if (this.enabled) {
return super.onTouchEvent(event);
}
return false;
}
@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
if (this.enabled) {
return super.onInterceptTouchEvent(event);
}
return false;
}
public void setPagingEnabled(boolean enabled) {
this.enabled = enabled;
} }
You just need to call the "setPagingEnabled" method with "false" and users won't be able to swipe to paginate.
