Android studio case-implement phone dialing .

1. SMS sending

1. Layout

.xml file

<EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="电话号码"
        android:inputType="number"
        android:id="@+id/num_btn"/>
    <EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="短信内容"
        android:id="@+id/mes_btn"/>
    <Button
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="发送"
        android:textColor="#ff0066"
        android:id="@+id/send_btn"/>

2. Code

.java file

public class message extends AppCompatActivity {
    
    
    EditText num_btn;
    EditText mes_btn;
    Button send_btn;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
    
    
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_message);
        num_btn=(EditText) findViewById(R.id.num_btn);
        mes_btn=(EditText) findViewById(R.id.mes_btn);
        send_btn=(Button) findViewById(R.id.send_btn);
        send_btn.setOnClickListener(new View.OnClickListener() {
    
    
            @Override
            public void onClick(View v) {
    
    
                Intent intent=new Intent();
                String strPhoneNum = num_btn.getText().toString();
                Uri uri = Uri.parse("smsto:"+strPhoneNum);
                String strMsg = mes_btn.getText().toString();
                intent.setAction(Intent.ACTION_SENDTO);
                intent.setData(uri);
                intent.putExtra("sms_body", strMsg);
                startActivity(intent);
            }
        });
        Toolbar toolbar = findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        FloatingActionButton fab = findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
    
    
            @Override
            public void onClick(View view) {
    
    
                Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                        .setAction("Action", null).show();
            }
        });
    }

3. Demo

Second, the camera is turned on

1. Code

The system camera is called, so there is no layout.
.java

 case R.id.type3_btn:
                intent.setAction(MediaStore.ACTION_IMAGE_CAPTURE);
                break;

2. Demo

3. Map

1. Code

case R.id.type4_btn:
                Uri uri = Uri.parse("geo:39.9,116.3");
                intent.setAction(Intent.ACTION_VIEW);
                intent.setData(uri);
                break;

2. Demo

Fourth, the total interface

1. Layout

.xml file

<Button
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="电话"
        android:textColor="#ff0066"
        android:background="#00FFF7"
        android:id="@+id/type1_btn"/>
    <Button
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="短信"
        android:textColor="#00aaff"
        android:background="#00ff00"
        android:id="@+id/type2_btn"/>
    <Button
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="相机"
        android:textColor="#899ad5"
        android:background="#ff00ff"

    <Button
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="地图"
        android:textColor="#00ff00"
        android:background="#ff0066"
        android:id="@+id/type4_btn"/>

2. Code

.java

public class MainActivity extends AppCompatActivity implements View.OnClickListener {
    
    
    Button type1_btn;
    Button type2_btn;
    Button type3_btn;
    Button type4_btn;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
    
    
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        type1_btn=(Button) findViewById(R.id.type1_btn);
        type2_btn=(Button) findViewById(R.id.type2_btn);
        type3_btn=(Button) findViewById(R.id.type3_btn);
        type4_btn=(Button) findViewById(R.id.type4_btn);
        type1_btn.setOnClickListener(this);
        type2_btn.setOnClickListener(this);
        type3_btn.setOnClickListener(this);
        type4_btn.setOnClickListener(this);
    }

    /**
     * Called when a view has been clicked.
     *
     * @param v The view that was clicked.
     */
    @Override
    public void onClick(View v) {
    
    
        Intent intent=new Intent();
        switch (v.getId()){
    
    
            case R.id.type1_btn:
                intent.setClassName("com.example.phone","com.example.phone.MainActivity");
                break;
            case R.id.type2_btn:
                intent.setClassName(this,"com.example.menu.message");
                break;
            case R.id.type3_btn:

                break;
            case R.id.type4_btn:
                Uri uri = Uri.parse("geo:39.9,116.3");
                intent.setAction(Intent.ACTION_VIEW);
                intent.setData(uri);
                break;
