List view item swipe left and swipe right?
Try this:
navigaList.setOnTouchListener(swipeDetector);
navigaList.setOnItemClickListener(listener);
OnItemClickListener listener = new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position,
long arg3) {
if(swipeDetector.swipeDetected()) {
if(swipeDetector.getAction() == Action.RL) {
} else {
}
}
};
SwipeDetector.java
public class SwipeDetector implements View.OnTouchListener {
public static enum Action {
LR, // Left to Right
RL, // Right to Left
TB, // Top to bottom
BT, // Bottom to Top
None // when no action was detected
}
private static final String logTag = "SwipeDetector";
private static final int MIN_DISTANCE = 100;
private float downX, downY, upX, upY;
private Action mSwipeDetected = Action.None;
public boolean swipeDetected() {
return mSwipeDetected != Action.None;
}
public Action getAction() {
return mSwipeDetected;
}
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN: {
downX = event.getX();
downY = event.getY();
mSwipeDetected = Action.None;
return false; // allow other events like Click to be processed
}
case MotionEvent.ACTION_MOVE: {

upY = event.getY();
float deltaX = downX - upX;
float deltaY = downY - upY;
// horizontal swipe detection

Android ListView Swipe Right and Left to Accept and Reject
Solution number 1 :
You Have to do like following to reach "near" to your functionality,
Wrap the adapter of your ListView
Like following :
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Create an Adapter for your content
String[] content = new String[20];
for (int i=0;i<20;i++) content[i] = "Row "+(i+1);
ArrayAdapter<String> stringAdapter = new ArrayAdapter<String>(
this,
R.layout.row_bg,
R.id.text,
new ArrayList<String>(Arrays.asList(content))
);
// Wrap your content in a SwipeActionAdapter
mAdapter = new SwipeActionAdapter(stringAdapter);
// Pass a reference of your ListView to the SwipeActionAdapter
mAdapter.setListView(getListView());
// Set the SwipeActionAdapter as the Adapter for your ListView
setListAdapter(mAdapter);
}
Create a background layout for each swipe direction
Like Following:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Create an Adapter for your content
String[] content = new String[20];
for (int i=0;i<20;i++) content[i] = "Row "+(i+1);
ArrayAdapter<String> stringAdapter = new ArrayAdapter<String>(
this,
R.layout.row_bg,
R.id.text,
new ArrayList<String>(Arrays.asList(content))
);
// Wrap your content in a SwipeActionAdapter
mAdapter = new SwipeActionAdapter(stringAdapter);
// Pass a reference of your ListView to the SwipeActionAdapter
mAdapter.setListView(getListView());
// Set the SwipeActionAdapter as the Adapter for your ListView
setListAdapter(mAdapter);
// Set backgrounds for the swipe directions
mAdapter.addBackground(SwipeDirections.DIRECTION_FAR_LEFT,R.layout.row_bg_left_far)
.addBackground(SwipeDirections.DIRECTION_NORMAL_LEFT,R.layout.row_bg_left)
.addBackground(SwipeDirections.DIRECTION_FAR_RIGHT,R.layout.row_bg_right_far)
.addBackground(SwipeDirections.DIRECTION_NORMAL_RIGHT,R.layout.row_bg_right);
}
You got both libraries and Example from the here :
https://github.com/wdullaer/SwipeActionAdapter
This will not exact like you want, but i hope this will help you so much to fulfilled your functionality.
Solution number 2 :
Solution 2 is about Changing some code in your Used code : http://www.tutecentral.com/android-swipe-listview/
i had try your code from the link http://www.tutecentral.com/android-swipe-listview/ and changing some code and successfully solve your problem(your confusion) about onOpened(..) method ( called left to right and vice versa )
First change :
custom_row.xml layout file has three button swipe_button1 to 3 ,
remove middle of them.Copy paste following code for remain two button :
<Button
android:id="@+id/swipe_button1"
android:layout_width="48dp"
android:layout_height="48dp"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:background="@drawable/your_accept_image" />
<Button
android:id="@+id/swipe_button3"
style="@style/MyListButtonAction"
android:layout_width="48dp"
android:layout_height="48dp"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:background="@drawable/your_reject_image" />
Remains code same for this layout.
Second change :
So now your accept and reject and list code is ready , now discuss about onOpened(..) method.
Confusion solution 1- You told , your onOpend(...) method called same both left to right and vice-verse
-> just to change following :
public void onOpened(int position, boolean toRight) {
if(toRight)
{
// for left to right your api calling here
swipelistview.closeAnimate(position);
}
else
{
// for right to left your api calling here
swipelistview.closeAnimate(position);
}
}
Confusion solution 2 when i take finger up it will must display entire listview or listview sides should retain it corners so its not working
-> i already answered it in above
called swipelistview.closeAnimate(position); in both if else, it hide left accept and right reject image when your your swipe left and right over.
So final code is following :
Entire cutom_row.xml layout
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"

}
adapter.notifyDataSetChanged();
}
public int convertDpToPixel(float dp) {
DisplayMetrics metrics = getResources().getDisplayMetrics();
float px = dp * (metrics.densityDpi / 160f);
return (int) px;
}
@Override
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;

}
Other code and library remains same, It helpful to you and other also, So enjoy.
