The simplest and fastest dialing tool for Android development (including the source code)

After learning for a week, I finally learned basic controls such as textview, editview, And button, and a little bit of layout. Then, Jia Ge (my master) asked me to write a phone call, it's amazing, but after a piece of his code, I think it's really easy ~~~ The following describes the specific operations:

First, let's take a look at my achievements:

1. Control Layout

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:background="@drawable/bg"    tools:context=".MainActivity" > <TextView        android:id="@+id/txv"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="@string/tishi"        android:textColor="#D2691E"        android:textSize="20dp" />    <LinearLayout        android:id="@+id/linOut1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_below="@id/txv"        android:orientation="horizontal" >        <Button            android:id="@+id/me"            android:layout_width="60dp"            android:layout_height="60dp"            android:layout_marginLeft="10dp"            android:layout_marginRight="20dp"            android:layout_marginTop="20dp"            android:layout_weight="1"            android:background="@drawable/niub" /></LinearLayout><LinearLayout        android:id="@+id/linOut_txt1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_below="@id/linOut1"        android:orientation="horizontal" >        <TextView            android:id="@+id/txv1"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_marginLeft="20dp"            android:layout_marginRight="10dp"            android:layout_weight="1"            android:text="@string/txv1" /></LinearLayout>

2. Code implementation:

package com.example.phone;import android.net.Uri;import android.os.Bundle;import android.app.Activity;import android.content.Intent;import android.view.Menu;import android.view.MenuItem;import android.view.View;import android.widget.Button;import android.widget.Toast;public class MainActivity extends Activity {private Button  niu;protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);onclick();               niu.setOnClickListener(new BtnOnlick());    }    private void onclick() {        niu = (Button) findViewById(R.id.niu);    }    private class BtnOnlick implements View.OnClickListener {public void onClick(View v) {switch (v.getId()) {                        case R.id.niu:getIntent("##########");break;                        default:break;                    }               }    }    private void getIntent(String str) {Intent i_ling = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + str));startActivity(i_ling);}}                                                

　　

Only one button and textview are used here. You can add them by yourself ~~~

3. Set permissions

Open androidmanifest. xml ----- and add the following code on the application Tag: <uses-Permission Android: Name = "android. Permission. call_phone"/>

4. Package (some of them need to be filled in as needed)

Right-click Project ----- export ----- andriod ----- export... ----- next --- next -----

5. Install and run it on your mobile phone. If you want to further study and exchange with us, you can add my new andriod group: 26040687. You are welcome to join us in learning and exchange ~~~~ Hahahaha
