Intent to call a number
Description
An application to call a telephone number.
Example
package com.java2s.app;
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.ViewGroup.LayoutParams;
import android.widget.Button;
import android.widget.LinearLayout;
//from ww w .j av a 2s .c om
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
LinearLayout parentContainer = new LinearLayout(this);
parentContainer.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.MATCH_PARENT));
parentContainer.setOrientation(LinearLayout.VERTICAL);
Button button = new Button(this);
parentContainer.addView(button);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent i = new Intent(android.content.Intent.ACTION_DIAL, Uri.parse("tel:+651234567"));
startActivity(i);
}
});
setContentView(parentContainer);
}
}
The code above generates the following result.
Note
You dial a specific number by passing in the telephone number in the data portion:
Intent i = new Intent(android.content.Intent.ACTION_DIAL,Uri.parse ("tel:+651234567"));
startActivity(i);
The dialer will display the number to be called. The user must still press the dial button to dial the number.
If you want to directly call the number without user intervention, change the action as follows:
Intent i = new Intent(android.content.Intent.ACTION_CALL,Uri.parse ("tel:+651234567"));
startActivity(i);
If you want your application to directly call the specified number, you need
to add the android.permission.CALL_PHONE permission to your application.
To display the dialer without specifying any number, simply omit the data portion, like this:
Intent i = new Intent(android.content.Intent.ACTION_DIAL);
startActivity(i);
