界面设计代码

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"xmlns:tools="http://schemas.android.com/tools"android:id="@+id/activity_main"android:layout_width="match_parent"android:layout_height="match_parent"tools:context=".MainActivity"android:orientation="vertical"><RelativeLayoutandroid:layout_width="match_parent"android:layout_height="wrap_content"android:orientation="horizontal"><ImageButtonandroid:id="@+id/btn_call"android:layout_width="120dp"android:layout_height="100dp"android:layout_alignParentLeft="true"android:layout_marginLeft="-2dp"android:background="@mipmap/call" /><ImageButtonandroid:id="@+id/btn_mail"android:layout_width="120dp"android:layout_height="100dp"android:layout_centerInParent="true"android:background="@mipmap/msg" /><ImageButtonandroid:id="@+id/btn_camera"android:layout_width="140dp"android:layout_height="100dp"android:layout_alignParentRight="true"android:background="@mipmap/photo"/></RelativeLayout><LinearLayoutandroid:layout_width="wrap_content"android:layout_height="wrap_content"android:orientation="horizontal"android:layout_marginTop="20dp"><EditTextandroid:layout_width="250dp"android:layout_height="wrap_content"android:id="@+id/et_phone1"android:textSize="20sp"android:onClick="onClick"android:hint="phoneNum"/></LinearLayout><ImageViewandroid:layout_width="match_parent"android:layout_height="match_parent"android:layout_marginTop="15dp"android:id="@+id/iv_pic"/></LinearLayout>

二.实现功能

1.可以从另一个Activity中,获得的不同的电话号码，实现电话拨打。

在MainActivity.java文件中具体实现代码

if (v.getId()==R.id.et_phone1){//点击号码编辑框，当前页面跳转到另一页面Intent intent = new Intent();intent.setClass(MainActivity.this,MessageActivity.class);startActivityForResult(intent,0);//0是请求码}else if (v.getId()==R.id.btn_call){Intent intent2 = new Intent();intent2.setAction(Intent.ACTION_CALL);intent2.addCategory(Intent.CATEGORY_DEFAULT);String num = et_phoneNum.getText().toString();intent2.setData(Uri.parse("tel:"+num));startActivityForResult(intent2,1)   ;

if(data == null) return;//获取电话号码的数据为空，不能拨号Bundle bundle = data.getExtras();if (requestCode==0){//请求码为0，获取号码String phoneNum = (String) bundle.get("phoneNum");et_phoneNum.setText(phoneNum);} else if (requestCode == 1) {//请求码为1，拨号String phoneNum=bundle.getString("phoneNum");et_phoneNum.setText(phoneNum);

2.可以打开相机拍照后，显示在图片框

在MainActivity.java文件中具体实现代码

else if (v.getId()==R.id.btn_camera){Intent intent1 = new Intent();intent1.setAction(MediaStore.ACTION_IMAGE_CAPTURE);//设置动作调用照相机startActivityForResult(intent1,REQUEST_CAMERA);

else if (requestCode==REQUEST_CAMERA){//请求码是获得照片Bitmap b = (Bitmap) bundle.get("data");//将data中的信息流解析为Bitmap类型iv_pic.setImageBitmap(b);//显示图片

3.可以发送短信

在MainActivity.java文件中具体实现代码

}else if (v.getId()==R.id.btn_mail){String num = et_phoneNum.getText().toString();Uri uri = Uri.parse("smsto:"+num);Intent intent3 = new Intent(Intent.ACTION_SENDTO,uri);startActivity(intent3);}
