The page I am working on has a javascript function executed to print parts of the page. For some reason, printing in Safari, causes the window to somehow update. I say somehow, because it does not really refresh as in reload the page, but rather it starts the "rendering" of the page from start, i.e. scroll to top, flash animations start from 0, and so forth. The effect is reproduced by this fiddle: http://jsfiddle.net/fYmnB/ Clicking the print button and finishing or cancelling a print in Safari causes the screen to "go white" for a sec, which in my real website manifests itself as something "like" a reload. While running print button with, let's say, Firefox, just opens and closes the print dialogue without affecting the fiddle page in any way. Is there something with my way of calling the browsers print method that causes this, or how can it be explained - and preferably, avoided? P.S.: On my real site the same occurs with Chrome. In the ex
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");
} });
