Simple RecyclerView example with filter option in Android

Hi Guys, Maybe you all are expert in terms of using RecyclerView in android. This blog is simple example for using filter option with RecyclerView adapter. As for now you will instantiate RecyclerView and set the adapter to RecyclerView as following way. RecyclerView list = (RecyclerView) findViewById(R.id.list); list.setLayoutManager(new LinearLayoutManager(this)); list.setHasFixedSize(true); ArrayList&ltNumber&gt numbers = new ArrayList&lt&gt(); String ONEs[] = {"ZERO", "ONE", "TWO", "THREE", "FOUR", "FIVE", "SIX", "SEVEN", "EIGHT", "NINE", "TEN"}; String TENs[] = {"ZERO", "TEN", "TWENTY", "THIRTY", "FOURTY", "FIFTY", "SIXTY", "SEVENTY", "EIGHTY", "NINETY", "HUNDRED"}; String HUNDREDS[] = {"ZERO", "HUNDRED", "TWO HUND

Translate Animation


     Translate Animation is used to move one object from one position to another position.

Signature is

public TranslateAnimation (float fromXDelta, float toXDelta, float fromYDelta,
float toYDelta)
      

The coding for set animation for particular object is including 4 steps.

  1. Have to configure our object. If it is imageview means
         
ImageView img = (ImageView) findViewById(R.id.image);

  2. Create animation.


TranslateAnimation moveLefttoRight = new TranslateAnimation(-1000, 0, 0, 0);
  3. Then most important we should set time delay for that animation. Otherwise we cant get animation feel.
moveLefttoRight.setDuration(2000);
  4. Set this animation to our object
img.startAnimation(moveLefttoRight);
  Full coding for set animation for a object is
ImageView img = (ImageView) findViewById(R.id.player1image);

TranslateAnimation moveLefttoRight = new TranslateAnimation(-1000, 0, 0, 0);  
moveLefttoRight.setDuration(2000);
moveLefttoRight.setFillAfter(true);
         
img.startAnimation(moveLefttoRight);
main.xml


    

    
AnimActivity.java
package com.android.anim;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.animation.TranslateAnimation;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;

public class ExActivity extends Activity {
 /** Called when the activity is first created. */
 int count = 0;
 String str1;
 ImageView img;

 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);

  Button b1 = (Button) findViewById(R.id.button1);
  final TextView tv1 = (TextView) findViewById(R.id.textview1);
  img = (ImageView) findViewById(R.id.player1image);

  final TranslateAnimation moveLefttoRight = new TranslateAnimation(
    -1000, 0, 0, 0);
  // moveLefttoRight.setInterpolator(new AccelerateInterpolator());
  moveLefttoRight.setDuration(2000);
  moveLefttoRight.setFillAfter(true);

  final TranslateAnimation moveLefttoRight1 = new TranslateAnimation(0,
    1000, 0, 0);
  // moveLefttoRight.setInterpolator(new AccelerateInterpolator());
  moveLefttoRight1.setDuration(2000);
  moveLefttoRight1.setFillAfter(true);

  img.startAnimation(moveLefttoRight);

  b1.setOnClickListener(new OnClickListener() {

   @Override
   public void onClick(View v) {
    // TODO Auto-generated method stub

    count++;
    Toast.makeText(getApplicationContext(), "Welcome",
      Toast.LENGTH_SHORT).show();
    str1 = "Button Pressed : " + count + " times.";
    tv1.setText(str1);    
    Log.i("count/2 is ", ""+count/2);
    if (count % 2 == 0)
     img.startAnimation(moveLefttoRight1);
    else
     img.startAnimation(moveLefttoRight);
   }
  });
 }
}


Run Project and feel the output.



Thank You

Simple example of OCRReader in Android.

Hi Friends, Maybe you all heard/used text scanning using camera feature or extracting text from Image. But this sample made it very easy for you. You can made it in very simple line of code. You can download the source code from OCRSample and import the library as a module into your project. Example usage : MainActivity.java public class MainActivity extends AppCompatActivity { private TextView textView; private final int CAMERA_SCAN_TEXT = 0; private final int LOAD_IMAGE_RESULTS = 1; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); textView = findViewById(R.id.textView); } @Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.menu_main, menu); return super.onCreateOptionsMenu(menu); } @Override public boolean onOptionsItemSele

Set limit for fraction in decimal numbers in EditText

            Already we know that we can set which type of input the edittext should accept from user using android:inputType="numberDecimal" But there is no predefined function to set the limit for the edittext to How many digit it should accept after the decimal point from user . We can achieve this by using TextWatcher . Full code example. Following program creates a Decimal Filter. DecimalFilter.java import android.text.Editable; import android.text.InputFilter; import android.text.TextWatcher; import android.view.KeyEvent; import android.view.View; import android.view.View.OnKeyListener; import android.widget.EditText; public class DecimalFilter implements TextWatcher { int count= -1 ; EditText et; Activity activity; public DecimalFilter(EditText edittext, Activity activity) { et = edittext; this.activity = activity; } public void afterTextChanged(Editable s) { if (s.length() > 0) { String str = et.getText().toString(); et.setOnKeyListener(new OnKeyL
