This example shows how you can create your own layout through code instead of xml.Algorithm:
1.) Create a new project by File-> New -> Android Project name it CodeLayoutExample.
2.) Run for output.
Steps:
1.) Create a project named CodeLayoutExample and set the information as stated in the image.
Build Target: Android 4.0
Application Name: CodeLayoutExample
Package Name: com. example. CodeLayoutExample
Activity Name: CodeLayoutExample
Min SDK Version: 11
Application Name: CodeLayoutExample
Package Name: com. example. CodeLayoutExample
Activity Name: CodeLayoutExample
Min SDK Version: 11
2.) Open CodeLayoutExample.java file and write following code there:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 | package com.example.codelayoutexample;import android.app.ActionBar.LayoutParams;import android.app.Activity;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.EditText;import android.widget.LinearLayout;import android.widget.TextView;import android.widget.Toast;public class CodeLayoutExample extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); LayoutParams params1 = new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT); TextView text = new TextView(this); text.setText("I am TextView"); text.setLayoutParams(params1); EditText edit = new EditText(this); edit.setHint("This is EditView...."); edit.setLayoutParams(params1); Button button = new Button(this); button.setText("Click me"); button.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Toast makeText = Toast.makeText(v.getContext(), "Clicked", Toast.LENGTH_SHORT); makeText.show(); } }); LinearLayout layout = new LinearLayout(this); layout.setOrientation(LinearLayout.VERTICAL); layout.setPadding(10, 10, 10, 10); layout.addView(text); layout.addView(edit); layout.addView(button); setContentView(layout); }} |
3.) Compile and build the project.
