You can set the click handler in xml with these attribute:
ReplyDeleteandroid:onClick="onClick"
android:clickable="true"
Don't forget the clickable attribute, without it, the click handler isn't called.
main.xml
...
<TextView
android:id="@+id/click"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Click Me"
android:textSize="55sp"
android:onClick="onClick"
android:clickable="true"/>
...
MyActivity.java
public class MyActivity extends Activity {
public void onClick(View v) {
...
}
}
OK I have answered my own question (but is it the best way?)
ReplyDeleteThis is how to run a method when you click or tap on some text in a TextView:
package com.textviewy;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.TextView;
public class TextyView extends Activity implements OnClickListener {
TextView t ;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
t = (TextView)findViewById(R.id.TextView01);
t.setOnClickListener(this);
}
public void onClick(View arg0) {
t.setText("My text on click");
}
}
and my main.xml is:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<LinearLayout android:id="@+id/LinearLayout01" android:layout_width="wrap_content" android:layout_height="wrap_content"></LinearLayout>
<ListView android:id="@+id/ListView01" android:layout_width="wrap_content" android:layout_height="wrap_content"></ListView>
<LinearLayout android:id="@+id/LinearLayout02" android:layout_width="wrap_content" android:layout_height="wrap_content"></LinearLayout>
<TextView android:text="This is my first text"
android:id="@+id/TextView01"
android:layout_width="wrap_content"
android:textStyle="bold"
android:textSize="28dip"
android:editable = "true"
android:clickable="true"
android:layout_height="wrap_content">
</TextView>
</LinearLayout>
This may not be quite what you are looking for but this is what worked for what I'm doing. All of this is after my onCreate.
ReplyDeleteboilingpointK = (TextView) findViewById(R.id.boilingpointK);
boilingpointK.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
if ("Boiling Point K".equals(boilingpointK.getText().toString()))
boilingpointK.setText("2792");
else if ("2792".equals(boilingpointK.getText().toString()))
boilingpointK.setText("Boiling Point K");
} });
