One Parent Linear layout is inflated and child views are added in the for-loop. But all child-view have the same id. I could find the id out by v.getId()
and then hardcode the id into the case "id of child view"
. But id might change on another phone.
In my case all ids are the same and to set them manually is probably also bad practice. I want to call the child-views by the onClick(View v)
-Method but can't get id right.
I added a tree view for illustration: tree view layout
@Override
public void onCreate(Bundle savedInstanceState) {
// extending existing parent class' methods
super.onCreate(savedInstanceState);
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
LinearLayout parent = (LinearLayout) inflater.inflate(R.layout.mainbase, null);
for (int i = 0; i < 4; i++) {
View custom = inflater.inflate(R.layout.identifierplate, null);
switch (i) {
case 0: {
//set layout images and text for first <include>
ImageView SensorReadout = (ImageView) custom.findViewById(R.id.sensor_icon);
SensorReadout.setImageResource(R.drawable.ic_launcher);
TextView sensor_name = (TextView) custom.findViewById(R.id.sensor_name);
sensor_name.setText(R.string.sr_1);
TextView sensor_description = (TextView) custom.findViewById(R.id.sensor_description);
sensor_description.setText(R.string.sr_2);
custom.setOnClickListener(this);
parent.addView(custom);
break;
}
case 1: {
// do same as in case 0 but different text/image
custom.setOnClickListener(this);
parent.addView(custom);
break;
}
default: { // Defaults are already set in the XML
}
}
}
setContentView(parent);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case 0: {
Intent intent = new Intent(this, First.class);
startActivity(intent);
break;
}
case 1: {
Intent intent = new Intent(this, Second.class);
startActivity(intent);
break;
}
default: {
int id = v.getId();
String ids = String.valueOf(id);
Toast.makeText(this, ids, Toast.LENGTH_SHORT).show(); //error: all have same id
}
}
}
How about using setTag and getTag method of childview ?
You can then check if getTag == first child and according code your logic.
In the for loop you can set tag using the setTag with i variable.
Mike M. pointed me into the right direction I added to .java:
custom.setId(R.id.id_v_2);
added to ids.xml:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<item
type="id"
name="id_v_0" />
<item
type="id"
name="id_v_1" />
</resources>
changed the onClick()
public void onClick(View v) {
switch (v.getId()) {
case R.id.id_v_0: { ...
