Android xml design slowing down my application

Android xml design slowing down my application - android

I have a layout design in my app.
It works smooth on emulator but when I open the App on a real device and scroll it, it scrolls rough I mean not smooth, too slow.
(I used android:largeHeap="true" otherwise it didn't work on my device but only on emulator.)
Can you help me to make it move smoothly?

I solved the problem by decreasing sizes of pictures in imageView.

Each widget and layout you add to your application requires initialization, layout, and drawing. For example, using nested instances of LinearLayout can lead to an excessively deep view hierarchy. Furthermore, nesting several instances of LinearLayout that use the layout_weight parameter can be especially expensive as each child needs to be measured twice. This is particularly important when the layout is inflated repeatedly, such as when used in a ListView or GridView.

ConstraintLayout is the new way to achieve the same flat xml structure. It will surely improve your response time

You can adjust the height of the bottom layout as per your requirement.

÷ hope any one fix this problem.

Make the height of the ScrollView as wrap_content as its height is determined at runtime. and also the same for its nested LinearLayout
To make the ImageView & TextView visible use android:gravity="center_vertical" for their surrounding LinearLayout
so change your layout to be:

Edit:
Anyone explain why its not showing my GridLayout width as match_parent
I want this :
Solution:
Changes:
Making Gridlayout width to match_parent
Adding android:layout_gravity="center" to the Gridlayout
Making the width & height of all CardViews and underlying
LinearLayouts to "wrap_content" >>>>>> This is the real cause to
the problem.
Making android:gravity="center" to the CardViews underlying
LinearLayout for symmetric purpose >> you can leave it as center_vertical if you wish.

android:layout_height="match_parent">
</androidx.constraintlayout.widget.ConstraintLayout>

Anyone explain why its not showing my GridLayout width as match_parent
I want this :

CardView inside GridLayout going off screen

I am using a GridLayout with CardViews inside of it to display a set of objects for users to click on and use to navigate around the app.
Everything appears to be fine on my tablet that I am testing on, but when I sent the APK to a friend, 2/3 of it runs off the screen and just doesn't seem to work.
Example screenshot:
The "Games" section here seems to work just fine. Unable to find any errors, I copy and pasted this section into the "Community" section and just re-named the icons so that the code would be identical except for a few strings.
I don't understand why one section will work and the others do not.

I had the same problem trying to align my GridLayout children (especially when using a CardView). I solved it by setting the following attributes for each child:
android:layout_columnWeight="1"
android:layout_gravity="fill_horizontal"
Like for example:
<GridLayout
android:id="#+id/grLayout_HelloWorld"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingTop="8dp"
android:paddingBottom="8dp"
android:columnCount="2"
android:rowCount="1"
android:useDefaultMargins="true">
<androidx.cardview.widget.CardView
android:id="#+id/crdView_simple_Card00"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_row="0"
android:layout_column="0"
android:layout_columnWeight="1"
android:layout_gravity="fill_horizontal"
app:cardBackgroundColor="#color/color_lime_shade1">
<TextView
android:id="#+id/txtView_TestCard00"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="My First Card" />
</androidx.cardview.widget.CardView>
<androidx.cardview.widget.CardView
android:id="#+id/crdView_simple_Card01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_row="0"
android:layout_column="1"
android:layout_columnWeight="1"
android:layout_gravity="fill_horizontal"
app:cardBackgroundColor="#color/color_lime_shade1">
<TextView
android:id="#+id/txtView_TestCard01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="My Second Card" />
</androidx.cardview.widget.CardView>
</GridLayout>
You will notice that i did not use the rowWeight attribute.
Disclaimer:
To be honest, I have no idea WHY this works... All I know is that it bothered me for some time, and I spent a lot of time on Google and StackOverflow until I found some info saying that fill_horizontal might be the solution... Then I just hacked my way from there, trying different layout attributes until I found columnWeight as well.
Hope this helps... Let me know if it works for you.
Good luck, brother (or sister) ✊

How To Fix Slow Rendering in my Android Code?

My app is running very slow when I Scroll Down. Please help me fix this issue.
I am concerned of this because of such articles that seem to say Google Play may penalize your app in the Play Store rankings if you fall in the bottom 25%.
All the project assets are present on this URL http://garudapixel.com/en/modern-dashboard-ui-design-android-studio-tutorial/
I want to make this type of layout in scrolling way...

Main Activity
package voidgoel.currentaffairs;

public class MainActivity extends AppCompatActivity {
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}

In my case I got the same problem. It was, images are very large. But your case you can also use recycle view with YourRecycleView.setLayoutManager(new GridLayoutManager(this,2)); within list. Images sizes are small is very important for that mode also. You can get some guide using below link.
