Intent Tutorial
The intent is described as moving from one point to another
The intent is of two types
- Explicit Intent:
- Explicit Intent is used to connect applications internally.
- For example, if we the known class name then we go from one activity to another…,
- So, here is the code
Main Activity
<?xml version = "1.0" encoding = "utf-8"?> <RelativeLayout xmlns:android = "http://schemas.android.com/apk/res/android" xmlns:tools = "http://schemas.android.com/tools" android:layout_width = "match_parent" android:layout_height = "match_parent"> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/btn_1" android:text="Activity 1" android:textColor="@color/white" android:layout_centerInParent="true"/> </RelativeLayout>
package com.example.myapplication; import androidx.appcompat.app.AppCompatActivity; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.widget.Button; public class MainActivity extends AppCompatActivity { Button button; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); button=findViewById(R.id.btn_1); button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Intent intent = new Intent(MainActivity.this,MainActivity2.class); startActivity(intent); } }); } }
This is the code by which you can go from one Activity to second Activity @Override public void onClick(View v) { Intent intent = new Intent(MainActivity.this,MainActivity2.class); startActivity(intent);
Main Activity 2
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity2"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:id="@+id/btn1" android:text="Activity 2" android:background="@color/purple_700" android:textColor="@color/white" android:textSize="25dp"/> </RelativeLayout>package com.example.myapplication; import androidx.appcompat.app.AppCompatActivity; import android.os.Bundle; public class MainActivity2 extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main2); } }
- Implicit Intent:
It has to be open any web page by using set Action() as shown
