android - 我正在尝试制作一个简单的应用程序，让您可以选择调用电话

Question

我的 droid 应用程序在主页上有一个按钮，它会为您提供一个对话弹出页面，并在对话页面中询问您是否要调用电话

我试了一遍又一遍，还没有完全弄清楚如何让按钮调用电话

我打开的java页面 打包 your.package2.phonecalls；

import android.app.Activity;
import android.app.Dialog;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class ButtonphonecallsActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    Button TheCallButton = (Button) findViewById(R.id.phonecallbutton);  
    TheCallButton.setOnClickListener(new View.OnClickListener() {  

        public void onClick(View v) {
            final Dialog dialog = new Dialog(ButtonphonecallsActivity.this);
            dialog.setContentView(R.layout.alertphonecall);
            dialog.setTitle("Zohan contact number");

            Button Nosir = (Button) dialog.findViewById(R.id.nobutton);  
            Nosir.setOnClickListener(new View.OnClickListener() {  
                @Override               
                public void onClick(View v) {
                    dialog.cancel();
                    } 
            });   

            Button Yessir = (Button) dialog.findViewById(R.id.yesbutton);
            Yessir.setOnClickListener(new OnClickListener() {
                @Override               
                public void onClick(View v) {
                    dialog.cancel();
                    startActivity(new Intent(ButtonphonecallsActivity.this, makingaphonecall.class));        
                }
            });

            dialog.show();
        }
    });
}
}

电话 Activity

package your.package2.phonecalls;

import android.app.Activity;
import android.content.ActivityNotFoundException;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;

public class makingaphonecall extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    call();
}

private void call() {
try {
    Intent callIntent = new Intent(Intent.ACTION_CALL);
    callIntent.setData(Uri.parse("tel:7578263678"));
    startActivity(callIntent);
} catch (ActivityNotFoundException activityException) {
     Log.e("helloandroid dialing example", "Call failed");
}
}

}

Answer 1

为什么要单独进行一个 Activity 来打电话？只需将以下两行添加到您的 onclick 中。

Intent dialer = new Intent(Intent.ACTION_CALL,Uri.parse("tel:7578263678"));
startActivity(dialer);
