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);

}

}

}
