Android Binding AppCompatEditText: Add TextWatcher

We should implement TextWatcher interface, due to listen to change text.

public TextWatcher getEditTextWatcher() {
    return new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence charSequence, int start, int count,
                int after) {

        }

        @Override
        public void onTextChanged(CharSequence charSequence, int start, int before, int count) {
            // FIXME: when change text
        }

        @Override
        public void afterTextChanged(Editable editable) {

        }
    };
}

set to app:addTextChangedListener on Layout file.

<data>
    <variable name="fragment"
              type="jp.baroqueworksdev.sample.SampleFragment"/>
</data>
<android.support.v7.AppCompatEditText
        app:addTextChangedListener="@{fragment.getEditTextWatcher}"/>

[Swift]how to use custom section header of TableView

We can use custom section header on UITableView.



Sub class : UITableViewHeaderFooterView

UITableViewHeaderFooterViewを継承したクラスを作成します。 We need to implement the sub class of UITableViewHeaderFooterView.

import UIKit

class CustomTableViewHeaderFooterView: UITableViewHeaderFooterView {

    @IBOutlet weak var headerView: UIView!
    
    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization code
    }
}


Nib file

We need to implement the view for Header.



Set to TableView

We need to use tableView.registerNib like a Cell. This is used return value in tableView:viewForHeaderInSection method.
If View width is no good, you need to set frame.size.

class ViewController: UITableViewController {
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let nib:UINib = UINib(nibName: "CustomTableViewHeaderFooterView", bundle: nil)
        tableView.registerNib(nib, forHeaderFooterViewReuseIdentifier: "CustomTableViewHeaderFooterView")
    }
    
    override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        return 1
    }
    
    // header height
    override func tableView(tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
        return 44
    }
    
    
    // header view
    override func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
        let header :CustomTableViewHeaderFooterView = self.tableView.dequeueReusableHeaderFooterViewWithIdentifier("CustomTableViewHeaderFooterView") as! CustomTableViewHeaderFooterView
        header.headerView.frame.size = CGRectMake(0, 0, tableView.frame.size.width, 44).size
        
        return header
    }
    
}

BottomSheet vis Android Design Support Library 23.2.0

Android Design Support Library had added BottomSheet from ver.23.2.
We can implement BottomSheet design like a GoogleMap.


AOSP: BottomSheetBehavior.java

Layout Sample

We add the param app:layout_behavior="@string/bottom_sheet_behavior" in child view of CoordinatorLayout.
<android.support.design.widget.CoordinatorLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:context=".MainActivity">

    <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical"
            app:layout_behavior="@string/bottom_sheet_behavior"
            app:behavior_peekHeight="240dp"
            app:behavior_hideable="false"
            android:background="@android:color/white">
        <TextView
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:text="BottomSheet Sample"/>
    </LinearLayout>
</android.support.design.widget.CoordinatorLayout>

We cab add following params.

  • app:behavior_peekHeight
    • BottomSheet minimum size
  • app:behavior_hideable
    • BottomSheet is hidden when scroll to bottom.

CoordinatorLayout has problem which registered to Issue Tracker.

CoordinatorLayout has problem which registered to Issue Tracker.

Do not show display when Screen rotate

If your Activity has configChanges that write on AndroidManifest.xml, CoordinatorLayout do not show display when screen rotate.
You can reproduct, Landscape to Portrait.


This had been registered to AOSP Issue Tracker.
CoordinatorLayout in design support library does not update child size on rotation
layout_behavior view height doesn't restore when keyboard goes down / ActionBar ActionView partially visible

AppBarLayout do not Animation

AppBarLayout do not Animation, release touch event.
I think we can implement show / dismiss animation with touch event listener and Behavior#onNestedFling.
Please advise us best practice.

Toolbar should settle when only partially scrolled

                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:inputType="textEmailAddress"
                android:hint="HintText"

Hot to use FloatingActionButton , Android Support library v22.2

Google had updated Android Support library!!
We can use the Design Support Library which include Material Design components.

http://developer.android.com/tools/support-library/index.html

import library

The following code is sample for Android Studio.
Note : typo in Android Developers site http://developer.android.com/tools/support-library/features.html#design

    compile 'com.android.support:design:22.2.0'

FloatingActionButton

The following code is sample for Layout.

    <android.support.design.widget.FloatingActionButton
            android:id="@+id/floating_action_button"
            android:layout_height="wrap_content"
            android:layout_width="wrap_content"
            android:src="@drawable/XXXX"
            android.support.design:backgroundTint="@color/fab_bg"
            android:contentDescription="@string/XXXX"/>
Default Fab Color is "colorAccent". If use other color, we can set android.support.design:backgroundTint.


Note

Design Library(ver 22.2) has some issues.
FAB doesn't have shadow on Lollipop https://code.google.com/p/android/issues/detail?id=175068
The FloatingActionButton has different margins on Lollipop and pre-Lollipop. https://code.google.com/p/android/issues/detail?id=175330

If not show "Shadow", set "app:borderWidth="0dp".

How to IntentsTestRule, in AndroidTest




About IntentsTestRule

IntentsTestRule is AndroidTest which can do intent test.

If use, we have to add Espresso-Intents library in build.gradle.
    androidTestCompile 'com.android.support.test.espresso:espresso-intents:2.1'

Test Sample

The following code is sample which Intent has Intent.ACTION_CALL by user operation.
@RunWith(AndroidJUnit4.class)
@LargeTest
public class MainActivityIntentTest {

    @Rule
    public IntentsTestRule<MainActivity> mActivityRule = new IntentsTestRule<>(
            MainActivity.class);

    @Before
    public void stubAllExternalIntents() {
        // By default Espresso Intents does not stub any Intents. Stubbing needs to be setup before
        // every test run. In this case all external Intents will be blocked.
        intending(not(isInternal()))
                .respondWith(new Instrumentation.ActivityResult(Activity.RESULT_OK, null));
    }

    @Test
    public void callPhone() {
        // call action
        onView(withId(R.id.callButton)).perform(click());

        // test
        intended(allOf(
                hasAction(Intent.ACTION_CALL),
                hasData("tel:0123456789"),
                toPackage("com.android.server.telecom")));

    }
}
How to create test class.
  • create test class with RunWith annotation
  • add IntentsTestRule with Rule annotation

We can check whether Intent has occurred.
  • Intended method which check the intended Intent
  • matches method


  • Add Intent to Starting Activity

    If need to add Intent to Activity, we need to do override IntentsTestRule#getActivityIntent.
        @Rule
        public IntentsTestRule<MainActivity> mActivityRule = new IntentsTestRule<>(MainActivity.class) {
    
            /**
            * add Intent to Activity
            */
            @Override
            protected Intent getActivityIntent() {
                Intent intent = new Intent();
                intent.putExtra(KEY_DATA,data);
                return intent;
            }
        };
