Question

here’s my code for main.xml

 <merge xmlns:android="http://schemas.android.com/apk/res/android">
 <RelativeLayout 
    android:id="@id/container" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    xmlns:android="http://schemas.android.com/apk/res/android">


<include layout="@layout/tabs" />

<ScrollView
    android:fillViewport="true" 
    android:scrollbars="@null"
    android:layout_height="fill_parent"
    android:layout_width="fill_parent">

    <LinearLayout 
        android:paddingTop="10dp"
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content"
        android:orientation="vertical" >

        <!-- first text_view -->
        <TextView 
            android:background="@color/grey"
            android:textColor="@color/white"
            android:text="@string/category" 
            android:id="@+id/category1" 
            android:layout_height="wrap_content" 
            android:layout_width="fill_parent"
            android:layout_marginTop="65dp" 
            android:textSize="17dp"
            android:typeface="serif"/>

        <!-- first horizontal_scrollview -->
        <HorizontalScrollView 
            android:scrollbars="@null"
            android:id="@+id/horizontalScrollView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content">

            <LinearLayout android:id="@+id/linearLayout1"
                android:orientation="horizontal" 
                android:visibility="visible"
                android:layout_height="wrap_content"
                android:layout_width="wrap_content">

                <!-- image_view should be here -->

            </LinearLayout>
        </HorizontalScrollView>
    </LinearLayout>
</ScrollView>
</RelativeLayout>
</merge>

here’s my code for tabs.xml

<?xml version="1.0" encoding="utf-8"?>
 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" 
android:background="#333333">

<TextView
    android:textColor="@color/gradient_green"
    android:id="@+id/viewall"
        android:layout_width="85dp"
        android:layout_height="25dp"
        android:layout_marginLeft="10dp"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:textSize="17dp"
        android:textStyle="bold" 
        android:text="@string/view_all"
        android:onClick="onClick"
        android:focusable="false"
        android:clickable="true" />

    <TextView
        android:textColor="@color/white"
        android:id="@+id/pic"
        android:layout_width="45dp"
        android:layout_height="25dp"
        android:layout_alignParentTop="true"
        android:layout_toRightOf="@+id/viewall"
        android:textSize="17dp"
        android:textStyle="bold" 
        android:text="@string/pic"
        android:onClick="onClick"
        android:focusable="false"
        android:clickable="true" />
</RelativeLayout>

and here’s the code inside the Main.java:

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

    TextView all = (TextView) this.findViewById(R.id.viewall);
    TextView pic = (TextView) this.findViewById(R.id.pic);

    all.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            TextView all = (TextView) findViewById(R.id.viewall);
            TextView pic = (TextView) findViewById(R.id.pic);

            Toast.makeText(Main.this, "VIEW ALL", Toast.LENGTH_SHORT).show();

            all.setTextColor(getResources().getColorStateList(R.color.gradient_green));
            pic.setTextColor(getResources().getColorStateList(R.color.white));
        }
    });

    pdf.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            TextView all = (TextView) findViewById(R.id.viewall);
            TextView pic = (TextView) findViewById(R.id.pic);

            Toast.makeText(Main.this, "VIEW ALL", Toast.LENGTH_SHORT).show();

            all.setTextColor(getResources().getColorStateList(R.color.white));
            pic.setTextColor(getResources().getColorStateList(R.color.gradient_green));
        }
    });

  }

so, if I set the setContentView() in the Main.class or Main.java as setContentView(R.layout.tabs) instead of setContentView(R.layout.main), the onClick() works, what should I do or what’s wrong with my code that hinders onClick() not to work?

Answer 1

Use these

 all = (TextView) this.findViewById(R.id.viewall);
 pdf = (TextView) this.findViewById(R.id.pic);

in on create and then set

all.setOnclickListener(this) in oncreate() method too.Implement onClicklistener when it will show error. it will work like a charm.

Edited

TextView btn=(TextView) findViewById(R.id.accInfo);
btn.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            //DO you work here
        }
    });

Setting Clicklistenner to TextView will automatically make it clickable so no need of

android:clickable="true"
