Dynamically View Designing in Android Java file : Layout in Java file in Android


Hi Friends!

I am going to share how to designe android view in Java file dynamically instead of xml file.

1-Print Screen for Application



2- DynamicUIDesigning.java

package hello.test.android;

import android.app.Activity;
import android.os.Bundle;
import android.widget.EditText;
import android.widget.LinearLayout;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import android.widget.TextView;

public class DynamicUIDesigning extends Activity {

String countryName[] = { "India", "Pakistan", "China", "Nepal", "Bangladesh" };

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.dynamic);

// Getting first layout from main.xml file
LinearLayout mLinearLayout = (LinearLayout) findViewById(R.id.linear1);
// create a loop how many time you want repeat the content
for (int k = 1; k < 5; k++) {

// create a base linear layout for linear1
LinearLayout mLinearLayout1 = new LinearLayout(this);
mLinearLayout1.setOrientation(0);
mLinearLayout.addView(mLinearLayout1);

// create dynamic text box and label
TextView title = new TextView(this);
title.setText("User Info-" + k);
// create name label
TextView name = new TextView(this);
name.setText("User Name:");
// create title2
TextView title2 = new TextView(this);
title2.setText("User Info-" + k);
// create city label
TextView city = new TextView(this);
city.setText("City of residence");
// create text box
EditText editName = new EditText(this);
editName.setText("User Name:");

// setting values of second layout in linear1
LinearLayout mLinearLayout2 = new LinearLayout(this);
mLinearLayout2.setOrientation(1);
mLinearLayout1.addView(mLinearLayout2);
mLinearLayout2.addView(title);
mLinearLayout2.addView(name);
mLinearLayout2.addView(editName);
// setting value of third layout in linear1
LinearLayout mLinearLayout3 = new LinearLayout(this);
mLinearLayout3.setOrientation(1);
mLinearLayout1.addView(mLinearLayout3);
mLinearLayout3.addView(title2);
mLinearLayout3.addView(city);

// create radio button
final RadioButton[] rb = new RadioButton[5];
RadioGroup rg = new RadioGroup(this); // create the RadioGroup
rg.setOrientation(RadioGroup.VERTICAL);// or RadioGroup.VERTICAL
for (int i = 0; i < 5; i++) {
rb[i] = new RadioButton(this);
rg.addView(rb[i]); // the RadioButtons are added to the
// radioGroup instead of the layout
rb[i].setText(countryName[i]);

}
mLinearLayout3.addView(rg);
}
}
}


3-dynamic.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/linearBase"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/linear1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
</LinearLayout>
</ScrollView>

</LinearLayout>
