click event on background image in android

Question

i put click event on this click_screen

<TextView
        android:id="@+id/textView1"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:onClick="click_screen" />

another activity's .java file (click_screen)

public void click_screen(View v)
{
    Intent click_screen=new Intent(this, MainActivity.class);
    startActivity(click_screen);
}

MainActivity.java

package com.amcct.amcostapp;

import android.annotation.SuppressLint;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;

public class MainActivity extends Activity 
{

    @SuppressLint("NewApi")
    protected void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

/*  @Override
    public boolean onTouchEvent(MotionEvent event) 
    {
        if (event.getAction() == MotionEvent.ACTION_DOWN) 
        {
            Intent click_screen=new Intent(this, MainActivity.class);
            startActivity(click_screen);
        }

        return super.onTouchEvent(event);
    }*/

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    public void click_screen(View v)
    {
        Intent click_screen=new Intent(this, MainActivity.class);
        startActivity(click_screen);
    }
}

===================================================================== .xml when i click anywhere it generates ^^ above click_screen

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:onClick="click_screen"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".Click_Page"
    android:background="@drawable/img_1" >

</RelativeLayout>

i think you have to add android:clickable=true, can't confirm though, i never set a clicklistener in xml — Suau, Sep 13 '13 at 17:49

Try setting onClick for the parent view of your xml instead. Something like.-

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:onClick="click_screen" >

...

</RelativeLayout>

Or just override onTouchEvent in your Activity like this.-

public boolean onTouchEvent(MotionEvent event) {
    if (event.getAction() == MotionEvent.ACTION_DOWN) {
        Intent click_screen=new Intent(this, MainActivity.class);
        startActivity(click_screen);
    }

    return super.onTouchEvent(event);
}

Myabe you can try this code, i make textview.setClickable(true)

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    final TextView textView = (TextView)findViewById(R.id.textView1);
    textView.setClickable(true);
    textView.setOnClickListener(this);
}

@Override
public void onClick(View view) {
    startActivity(new Intent(this, MainActivity.class));
}

You want to move to a different activity when clicked anywhere on screen?then why are you setting the onclick on that textview?set the onclick attribute on the top relative layout/Linear layout instead of setting on the textview.

Your code is in MainActivity and through intent you are again trying to go to the MainActivity.class? specify the activity to which you want to go to for eg:

Intent click_screen=new Intent(MainActivity.this, nextActivity.class);
    startActivity(click_screen);
