The second will allow the user to view and edit details of a single image (these are details that you choose and do not need to be permanent). The third will allow the user to view the selected image in full screen. +This will encompass many of the skills you have developed over the Intro to Android course. We'll give you a few tips on how to process. + +### Part 1 - Create an Android Studio Project + +1. Create a new Android Studio project +2. Name the project "Image Viewer" +3. Make sure that the target API level is below that of your testing environment. + +### Part 2 - Build layout for the Add and List activity + +1. Open the app's activity_main.xml file. +2. Change the parent viewgroup to a linear layout +> Set the `orientation` attribute to `vertical` to best utilize the screen real estate +4. Add a `ScrollView` to list all previously viewed images. Give it a linear layout child. +5. Add a `Button` so the user select an image to add to the list +6. Add IDs to all the views that will need to be accessed in the code. + +### Part 3 - Create an ImageData Class + +1. Create a class to store desired data from retreived image. +> The only required data is a name and a `Uri` stored as a String. +> Convert a `Uri` to a string with `.toString()` method and back with `Uri.parse(stringUri)`. +2. Class must contain the keywords `implements Serializable` in the class signature +> This provides the necessary methods to the `Intent.putExtra` method can store the class's data +3. Make all the data members private and create getters and setters for them +> The `Uri` setter should convert the `Uri` to a `String` and the getter should convert it back. +> This is because a `Uri` object can't be serialized. + +### Part 4 - Write a method to generate a TextView object + +1. Add a `TextView` to your layout xml file. +2. Manipulate its attributes until you find a design that you like. +3. Write a method that will create a `TextView` object and add those attributes to it programatically. +4. The method must accept a `String` to be the view's text attribute and an `int` which is the index where the element is stored in the `List`. +5. Return the `TextView` from the method. +6. To add the `TextView` to the ui, pass it to your `ScrollView`'s `LinearLayout` child's `.addView()` method. + +### Part 5 - Create an Intent to Get an Image + +1. Create a listener and event handler for the add button in MainActivity.java +2. In the click event method, write a Get Content Implicit Event that retreives an image from the system. +3. Broadcast that intent with a `startActivityForResult` method call. +4. Override the `onActivityResult` method to create the `ImageData` object, add it to an `ArrayList` class data memeber have a `TextView` generated and added to your UI. + +### Part 6 - Test your App + +1. Thoroughly test this activity before moving on. + +### Part 7 - Add a click listener to the items in the list + +1. In your `TextView` generator give the `TextView` object a listener that will get the tag from the element, use that to pull the `ImageData` object from the `List`. +2. Use `intent.putExtra()` to add the object to the intent + +### Part 8 - Build the layout for the details activity + +1. Design a layout that will display details about the file. +2. Display the image somewhere in the layout. + +### Part 9 - Retreive the Object from the Intent + +1. Use `getIntent()` to get the intent used to launch this activity. +2. Use the `intent.getSerializableExtra()` method to retreive the serialized data and then cast it to `ImageData`. + * the final line of code should look something like this `myObject = (ImageData)intent.getSerializableExtra("KEY")` + +### Part 10 - Display object + +1. Show the desired data in the UI. +2. Use `.setImageURI()` to get the image for your `ImageView` to the one in our `ImageData` + +### Part 11 - Test your App + +1. Thoroughly test these two activities before moving on. + + +## Challenge (Optional) +### Part 12 - Build Fullscreen Layout + +1. Add an activity +> You can pick a Fullscreen activity from the new activity wizard and adapt it to your needs, or build an empty activity with full screen imageview element +2. Adapt generated layout to fit your needs + +### Part 13 - Built an intent to go to the next activity + +1. Build an intent to go to the next activity, but instead of passing the whole object, just pass the `String` value for the Uri. + +### Part 14 - Add the image to the UI + +1. Use the `intent.getStringExtra()` method to retreive the `String` `Uri` from the `Intent` +2. Use `.setImageURI()` to update the `Uri` + +### Submit +Send your completed app to your Project Manager. diff --git a/Android_Intents_ActivityLifeCycle/S01M01 - Intents.pdf b/Android_Intents_ActivityLifeCycle/S01M01 - Intents.pdf new file mode 100644 index 0000000..8410f7d Binary files /dev/null and b/Android_Intents_ActivityLifeCycle/S01M01 - Intents.pdf differ diff --git a/Android_Intents_ActivityLifeCycle/app/.gitignore b/Android_Intents_ActivityLifeCycle/app/.gitignore new file mode 100644 index 0000000..796b96d --- /dev/null +++ b/Android_Intents_ActivityLifeCycle/app/.gitignore @@ -0,0 +1 @@ +/build diff --git a/Android_Intents_ActivityLifeCycle/app/build.gradle b/Android_Intents_ActivityLifeCycle/app/build.gradle new file mode 100644 index 0000000..5cfce3d --- /dev/null +++ b/Android_Intents_ActivityLifeCycle/app/build.gradle @@ -0,0 +1,28 @@ +apply plugin: 'com.android.application' + +android { + compileSdkVersion 28 + defaultConfig { + applicationId "com.example.imageveiwer3" + minSdkVersion 15 + targetSdkVersion 28 + versionCode 1 + versionName "1.0" + testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" + } + buildTypes { + release { + minifyEnabled false + proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro' + } + } +} + +dependencies { + implementation fileTree(dir: 'libs', include: ['*.jar']) + implementation 'com.android.support:appcompat-v7:28.0.0' + implementation 'com.android.support.constraint:constraint-layout:1.1.3' + testImplementation 'junit:junit:4.12' + androidTestImplementation 'com.android.support.test:runner:1.0.2' + androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2' +} diff --git a/Android_Intents_ActivityLifeCycle/app/proguard-rules.pro b/Android_Intents_ActivityLifeCycle/app/proguard-rules.pro new file mode 100644 index 0000000..f1b4245 --- /dev/null +++ b/Android_Intents_ActivityLifeCycle/app/proguard-rules.pro @@ -0,0 +1,21 @@ +# Add project specific ProGuard rules here. +# You can control the set of applied configuration files using the +# proguardFiles setting in build.gradle. +# +# For more details, see +# http://developer.android.com/guide/developing/tools/proguard.html + +# If your project uses WebView with JS, uncomment the following +# and specify the fully qualified class name to the JavaScript interface +# class: +#-keepclassmembers class fqcn.of.javascript.interface.for.webview { +# public *;
