Menu
I want to build a category list scrollview in android studio using java. I having truble to understand how to pass value from TextView to anthor TextView with same value in other activity.
activity_first.xml
“`
<TextView
android:id=”@+id/PersonName”
android:layout_width=”match_parent”
android:layout_height=”wrap_content”
android:ems=”10″
android:textColorHint=”@color/black”
android:background=”@android:color/transparent”
android:text=”Name” />
FirstActivity.java
“`
public class FirstActivity extends AppCompatActivity {
TextView PersonName;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_first);
PersonName = (TextView)findViewById(R.id.PersonName);
PersonName.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent p = new Intent(FirstActivity.this, SecondActivity.class);
startActivity(p);
}
});
}
}
In second activity i have a scrollview.
activity_second.xml
“`
<ScrollView
android:layout_width=”match_parent”
android:layout_height=”match_parent”>
<LinearLayout
android:layout_width=”match_parent”
android:layout_height=”wrap_content”
android:orientation=”vertical” >
<TextView
android:id=”@+id/textView”
android:layout_width=”match_parent”
android:layout_height=”wrap_content”
android:text=”Father” />
<TextView
android:id=”@+id/textView2″
android:layout_width=”match_parent”
android:layout_height=”wrap_content”
android:text=”Mother” />
</LinearLayout>
</ScrollView>
in activity_second.xml when I press on TextView it will return me with the value Father (id:textView) to the FirstActivity and change the TextView (id: PersonName) to father and if I’ll do it with value mother (id:textView2) it will do same action and return me to FirstActivity.
