Hello.
I have an application that launch a thread when a ToggleButton is
pressed, but if I press the home button, a new activity is started (I
can return to the first activity if I press the back button), but I
want to recovery the first activity launched state, which have the
reference of the initial thread.
This is my code:
org.test.test.java:
package org.test;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.TextView;
import android.widget.ToggleButton;
public class test extends Activity {
private Thread mRefresh;
private int mCounter = 0;
private ToggleButton mStartStopButton;
private TextView mTexStat;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mStartStopButton = (ToggleButton) findViewById
(R.id.startstop);
mTexStat = (TextView) findViewById(R.id.textStat);
mStartStopButton.setOnClickListener(new View.OnClickListener
() {
public void onClick(View v) {
if (mStartStopButton.isChecked()) {
mRefresh = new Thread(new Runnable() {
@Override
public void run() {
while (true) {
try {
Thread.sleep(1000);// 1
second
mCounter++;
} catch (InterruptedException
e) {
Log.e("test", "Error
sleeping", e);
}
}
}
});
//Start the thread
startThread();
} else {
// Stop thread an show the counter
stopThread();
}
}
});
}
private void stopThread() {
mRefresh.stop();
mTexStat.setText("Stopped, Counter = " + mCounter);
}
private void startThread() {
mRefresh.start();
mTexStat.setText("Started");
}
}
this is the mail.xml:
<?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:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="3dip">
<TextView android:layout_width="wrap_content"
android:id="@+id/textStatus"
android:layout_height="wrap_content"
android:text="Status:" />
<TextView android:text=""
android:id="@+id/textStat"
android:padding="3dip"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<RelativeLayout android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<ToggleButton
android:id="@+id/startstop"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
/>
</RelativeLayout>
</LinearLayout>
</LinearLayout>
And this is my manifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android";
package="org.test"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/
app_name">
<activity android:name=".test"
android:label="@string/app_name"
android:clearTaskOnLaunch="false"
android:allowTaskReparenting="false">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category
android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<uses-sdk android:minSdkVersion="3" />
</manifest>
Anybody knows how to solve this problem?
Sorry for my English.
