Action_call代码Android Studio M中的Broblem

Question

当我单击callbutton时，我的程序停止了什么问题

public void callbutton(View v) {  try{
             intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:111*"+phone+"#"));
            startActivity(intent);
            }catch (ActivityNotFoundException e){
                Toast.makeText(data.this, "noooo", Toast.LENGTH_SHORT).show();
            }}

**我在清单中写了许可**

<uses-permission android:name="android.permission.CALL_PHONE" />

Answer 1

应该像这个

public void callbutton(View v) {
    try {
        Intent intent = new Intent(Intent.ACTION_CALL);
        intent.setData(Uri.parse("tel:[phone]"));
        startActivity(intent);
    }catch (ActivityNotFoundException e){
        Toast.makeText(Activity.this, "noooo", Toast.LENGTH_SHORT).show();
    }
}

在API 23或更高版本上：您最使用此代码：

public void calling(String phoneNumber) {
    Intent intent = new Intent(Intent.ACTION_CALL);
    intent.setData(Uri.parse(phoneNumber));
    if (intent.resolveActivity(getPackageManager()) != null) {
        startActivity(intent);
    }
}

or ::

public void callind(String phone) {
    Intent callIntent = new Intent(Intent.ACTION_CALL); //use ACTION_CALL class
    callIntent.setData(Uri.parse(phone));    //this is the phone number calling
    //check permission
    //If the device is running Android 6.0 (API level 23) and the app's targetSdkVersion is 23 or higher,
    //the system asks the user to grant approval.
    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
        //request permission from user if the app hasn't got the required permission
        ActivityCompat.requestPermissions(this,
                new String[]{Manifest.permission.CALL_PHONE},   //request specific permission from user
                10);
        return;
    }else {     //have got permission
        try{
            startActivity(callIntent);  //call activity and make phone call
        }
        catch (android.content.ActivityNotFoundException ex){
            Toast.makeText(getApplicationContext(), "did not work", Toast.LENGTH_SHORT).show();
        }
    }
}

在API 23及更少：您可以使用此代码：

public void callind(String phoneNumber) {
    Intent intent = new Intent(Intent.ACTION_CALL);
    intent.setData(Uri.parse(phoneNumber));
        startActivity(intent);
    }
}

在拖曳方面，您必须添加清单权限：

<uses-permission android:name="android.permission.CALL_PHONE" />
