ACTION_DIAL не может найти Intent при нажатии кнопки вызова

Question

Я использую ImageView для извлечения данных из TextView и использую его для вызова ACTION_DIAL.Всякий раз, когда приложение запускается, оно не может запустить номеронабиратель для отображения номера.Это показывает, что getPackageManger является нулевым.Я добавил код с XML ниже.Если я удалю оператор else ниже, приложение вылетит.

Код:

import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.support.v7.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.view.View;
import android.widget.ImageView;
import android.widget.TextView;

import com.squareup.picasso.Picasso;

public class PostDetailActivity extends AppCompatActivity {

    TextView mTitleTv, mDetailTv, mCategoryTv, mCallTv;

    ImageView mImageIv;

    private static final String TAG = "PostDetailActivity";


    String contact;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_post_detail);

        //Action Bar
        ActionBar actionBar = getSupportActionBar();

        // ActionBar title
        actionBar.setTitle("Coupon Details");

        // Set Back Button
        actionBar.setDisplayHomeAsUpEnabled(true);
        actionBar.setDisplayShowHomeEnabled(true);


        // Initialise
        mTitleTv = findViewById(R.id.titleTv);
        mDetailTv = findViewById(R.id.descriptionTv);
        mImageIv = findViewById(R.id.imageView);
        mCategoryTv = findViewById(R.id.categoryTv);

        mCallTv = findViewById(R.id.callTv);

        // get data from intent
        String image = getIntent().getStringExtra("image");
        String title = getIntent().getStringExtra("title");
        String desc = getIntent().getStringExtra("description");
        String cate = getIntent().getStringExtra("category");

        String call = getIntent().getStringExtra("contact");

        contact = call;

        // Set Data to views
        mTitleTv.setText(title);
        mDetailTv.setText(desc);
        mCategoryTv.setText(cate);

        mCallTv.setText(call);

        Picasso.get().load(image).into(mImageIv);

    }

    // Handle onBack pressed to go back to the previous activity

    @Override
    public boolean onSupportNavigateUp() {
        onBackPressed();
        return true;
    }


    public void dialNumber(View view) {
        TextView textView = (TextView) findViewById(R.id.callTv);
        // Use format with "tel:" and phone number to create phoneNumber.
        String phoneNumber = String.format("",
                textView.getText().toString().trim());

//        String phoneNumber = "1234567890";

        // Create the intent.
        Intent dialIntent = new Intent(Intent.ACTION_DIAL);
        // Set the data for the intent as the phone number.
        dialIntent.setData(Uri.parse(phoneNumber));
        // If package resolves to an app, send intent.
        if (dialIntent.resolveActivity(getPackageManager()) != null) {
            startActivity(dialIntent);
        } else {
            Log.e(TAG, "Can't resolve app for ACTION_DIAL Intent.");
        }
    }

}

Answer 1

Заменить

String phoneNumber = String.format("", textView.getText().toString().trim());

на

 String phoneNumber = String.format("tel:%s", textView.getText().toString().trim());

В качестве первого оператора будет получена пустая строка.
