My App Crashes When I Clicked the Button Which Will Take Me the Another Activity on Java, Android Studio

My app crashes when I clicked the button which will take me the another Activity on Java, Android Studio

Change android:src="@+id/micc" to android:src="@drawable/micc" /> in ImageButton. It's causing the problem.

Android Studio Kotlin: Button continually causes crashes when clicked

I finally found the error. Your Button has the same name like the Activity that will be used for intent. Change it to this:

package com.smvcalculator

import android.content.Intent
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.widget.Button

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        val maleLP_button = findViewById<Button>(R.id.malebtn) //new button name
        maleLP_button.setOnClickListener {
            val intent = Intent(this, MaleLP::class.java) //different to class name
            startActivity(intent)
        }
    }
}

Now it should work :)

App crashes when a button is used to invoke a new activity

Update your button xml code to this :

<Button
    android:text="About"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_above="@+id/textView6"
    android:layout_centerHorizontal="true"
    android:id="@+id/button2"
    style="@style/Widget.AppCompat.Button.Borderless"
    android:background="?android:attr/colorBackground"
    android:backgroundTint="?android:attr/colorBackground"
    android:onClick="button2" />

What above code is doing is it will trigger the method button2 of your activity. Earlier it was searching for following method name: button2 (BitRates) in your acitvity

button.setOnClickListener is crashing my app. Kotlin 1.3.72

Through the help of this post and more research I found a solution.
I knew my problem was the creating/calling of the button. My button was not located in my main activity xml file but in another. So in my adapter is where I had to put the code.

        val itemView = LayoutInflater.from(parent.context).inflate(R.layout.table_list_item, parent, false)
        return RowViewHolder(itemView)


    }

        view.setBackgroundResource(R.drawable.table_header_cell_bg)

            }
        }
