thank you

If those CardView will contain different data you can use a RecyclerView and on button click you can add an item in the list and notify the adapter this will add a new item(here item is your CardView created in a different XML file) on screen.
This could be helpful

ButterKnife #onClick method for Button view is not working

I was updating an existing code by introducing dismiss button, and the onClick Butterknife method is not working for dismiss button, whereas its working for close button. In the below code, I am enabling the close button for some devices and for other devices I am enabling the dismiss button. I am quite unsure why this "dismiss" button is not working, whereas the close button is working fine. And both of them use the ButterKnife, onClick method - onSkip()
InfoActivity.java :
public class InfoActivity extends BccActiviy {
#BindView(R.id.ImageView_CloseView)
ImageView tCloseView;
#BindView(R.id.Dismiss)
Button tDismiss;
.....
#OnClick({R.id.Dismiss, R.id.ImageView_CloseView})
public void onSkip(View v) {
onDissmissPressed();
}
public void initialize(Bundle savedInstanceState) {
if (tConfig.isDismiss()) {
tCloseView.setVisibility(View.GONE);
tDismiss.setVisibility(View.VISIBLE);
} else {
tDismiss.setVisibility(View.GONE);
}
}
}

Try removing the onClick from xml.

android alertdialog theme inconsistency error

I have an alert dialog which popups when you click a button in my app. The code is pretty simple and can be seen below:
final String[] options = {"Bar Graph", "Pie Chart", "Text Summary"};
AlertDialog.Builder builder = new AlertDialog.Builder(myActivity.this);
builder.setTitle("Choose a summary");
builder.setIcon(R.drawable.summaryicon);
builder.setItems(options, ... );
See below an image of what it looks like. This is good.
However, strangely sometimes when I build my app on the emulator the theme of the alert dialog changes and looks like this instead:
I cannot imagine what would be causing this random change in a seemingly unpredictable way.
I have tried using this line to set the theme manually, but it seems to have no effect.
ContextThemeWrapper themedContext = new ContextThemeWrapper( AnalysisActivity.this, android.R.style.ThemeOverlay_Material_Dialog_Alert );
AlertDialog.Builder builder = new AlertDialog.Builder(themedContext);
...
I am confused and looking for a way to set the theme manually or ensure it doesn't change from the default.
I can't entirely tell if the rest of my app also experiences the same theme change because most has all been overridden by custom code, but I don't believe it is changing. Any ideas would be welcome.
Note: this alternate theme looks like an older theme so perhaps there is some version issue?

try this code...
step-1: create layout file of your alert dialog(this layout is your designed alertDialog)
step-2: and use this code
public void displayAlertDialog() {
LayoutInflater factory = LayoutInflater.from(this);
final View alertDialogView = factory.inflate(R.layout.alert_dialog, null);
final AlertDialog alertDialog = new AlertDialog.Builder(this).create();
alertDialog.setView(alertDialogView);
alertDialogView.findViewById(R.id.bar_graph).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//your business logic
alertDialog.dismiss();
}
});
alertDialogView.findViewById(R.id.pie_chart).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//your business logic
alertDialog.dismiss();
}
});
alertDialogView.findViewById(R.id.text_summary).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//your business logic
alertDialog.dismiss();
}
});
alertDialog.show();
}

Along with Dinesh Sarma's answer the code I have now implemented to create the alertdialog activity can be seen here.
It creates a layout that looks like this:
Use this layout code in a file called alert_dialog.xml:

I have searched and tried a lot for edit text visibilty but not finding any proper reason when i give the background to xml file like any color it displays. But in the white background it is not visible . Please guide me for the mentioned issue.

You can change color of floating labels using theme, just add below code in your styles.xml
<style name="TextAppearence.App.TextInputLayout" parent="#android:style/TextAppearance">
<item name="android:textColor">#color/red</item>
<item name="android:textSize">14sp</item>
</style>
And then apply this theme to you TextInputLayout
<android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColorHint="#color/gray"
app:hintTextAppearance="#style/TextAppearence.App.TextInputLayout">
<android.support.v7.widget.AppCompatEditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="#string/hint" />
</android.support.design.widget.TextInputLayout>

I am trying to create custom TextInputLayout. How can I create below custom TextInputLayout?

You should use Material Design style for Outline Box. Just simple use:
style="#style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
in TextInputLayout. See Text Field for Android in Material Design Guide

Here is an workaround:
1. Design your layout structure as below:
activity_test.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:padding="16dp"
android:background="#android:color/white">
<!-- Username -->
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<View
android:layout_width="match_parent"
android:layout_height="52dp"
android:layout_marginTop="10dp"
android:background="#drawable/bg_rounded_input_field" />
<TextView
android:id="#+id/text_dummy_hint_username"
android:layout_width="wrap_content"
android:layout_height="2dp"
android:layout_marginTop="10dp"
android:layout_marginLeft="16dp"
android:paddingLeft="4dp"
android:paddingRight="4dp"
android:text="Username"
android:textSize="16sp"
android:background="#android:color/white"
android:visibility="invisible"/>
<android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp"
android:hint="Username"
android:textColorHint="#android:color/black"
app:hintTextAppearance="#style/HintTextStyle">
<EditText
android:id="#+id/edit_username"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="text|textCapWords"
android:maxLines="1"
android:backgroundTint="#android:color/transparent"/>
</android.support.design.widget.TextInputLayout>
</RelativeLayout>
<!-- Password -->
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="8dp">
<View
android:layout_width="match_parent"
android:layout_height="52dp"
android:layout_marginTop="10dp"
android:background="#drawable/bg_rounded_input_field" />
<TextView
android:id="#+id/text_dummy_hint_password"
android:layout_width="wrap_content"
android:layout_height="2dp"
android:layout_marginTop="10dp"
android:layout_marginLeft="16dp"
android:paddingLeft="4dp"
android:paddingRight="4dp"
android:text="Password"
android:textSize="16sp"
android:background="#android:color/white"
android:visibility="invisible"/>
<android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp"
android:hint="Password"
android:textColorHint="#android:color/black"
app:hintTextAppearance="#style/HintTextStyle">
<EditText
android:id="#+id/edit_password"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="textPassword"
android:maxLines="1"
android:backgroundTint="#android:color/transparent"/>
</android.support.design.widget.TextInputLayout>
</RelativeLayout>
</LinearLayout>
2. Use below drawable bg_rounded_input_field.xml for rounded corners.
res/drawable/bg_rounded_input_field.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<stroke
android:color="#android:color/black"
android:width="2dp">
</stroke>
<corners
android:radius="8dp">
</corners>
</shape>
3. Use below HintTextStyle to TextInputLayout by adding attribute app:hintTextAppearance="#style/HintTextStyle".
res/values/styles.xml
<style name="HintTextStyle" parent="TextAppearance.Design.Hint">
<item name="android:textSize">16sp</item>
</style>
4. Finally, in your Activity just show/hide TextView text_dummy_hint_username and text_dummy_hint_password
during focus change.
FYI, I have used Handler with delay 100 millis to
show the dummy hints TextView to sync with TextInputLayout hint text
animation.
TestActivity.java
import android.os.Handler;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
import android.widget.TextView;
public class TestActivity extends AppCompatActivity {
TextView textDummyHintUsername;
TextView textDummyHintPassword;
EditText editUsername;
EditText editPassword;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test);
textDummyHintUsername = (TextView) findViewById(R.id.text_dummy_hint_username);
textDummyHintPassword = (TextView) findViewById(R.id.text_dummy_hint_password);
editUsername = (EditText) findViewById(R.id.edit_username);
editPassword = (EditText) findViewById(R.id.edit_password);
// Username
editUsername.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
// Show white background behind floating label
textDummyHintUsername.setVisibility(View.VISIBLE);
}
}, 100);
} else {
// Required to show/hide white background behind floating label during focus change
if (editUsername.getText().length() > 0)
textDummyHintUsername.setVisibility(View.VISIBLE);
else
textDummyHintUsername.setVisibility(View.INVISIBLE);
}
}
});
// Password
editPassword.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
// Show white background behind floating label
textDummyHintPassword.setVisibility(View.VISIBLE);
}
}, 100);
} else {
// Required to show/hide white background behind floating label during focus change
if (editPassword.getText().length() > 0)
textDummyHintPassword.setVisibility(View.VISIBLE);
else
textDummyHintPassword.setVisibility(View.INVISIBLE);
}
}
});
}
}
OUTPUT:
Hope this will help~
