我需要帮助获取GPS位置并通过短信发送它以及相关消息。我开发了一个紧急按钮应用程序,它应该发送自定义消息+ GPS位置。我正在努力实施GPS定位功能。
没有GPS的原始代码: / 此代码很好用,但它不包含GPS位置 /
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.telephony.SmsManager;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class MainActivity extends AppCompatActivity {
private EditText customMessage;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
customMessage=(EditText)findViewById(R.id.customMessage);
}
public void sendText(View view)
{
String message = "";
if (view.getId() == R.id.fab)
{
message = customMessage.getText().toString();
}
else
{
Button sender = (Button)view;
message = sender.getText().toString();
}
//Toast.makeText(this, "Test", Toast.LENGTH_SHORT).show();
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage("6505551212", null,message + "(Location Here)", null, null);
}
}
GPS代码: / 代码的问题是当我点击发送按钮时应用程序崩溃但它没有错误 /
import android.location.Location;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.telephony.SmsManager;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class MainActivity extends AppCompatActivity {
private EditText customMessage;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
customMessage=(EditText)findViewById(R.id.customMessage);
}
public void sendText (View view, String phoneNumber, Location currentLocation) {
String message = "";
if (view.getId() == R.id.fab)
{
message = customMessage.getText().toString();
}
else
{
Button sender = (Button)view;
message = sender.getText().toString();
}
SmsManager smsManager = SmsManager.getDefault();
StringBuffer smsBody = new StringBuffer();
smsBody.append("http://maps.google.com?q=");
smsBody.append(currentLocation.getLatitude());
smsBody.append(",");
smsBody.append(currentLocation.getLongitude());
smsManager.sendTextMessage("6505551212", null, smsBody.toString(), null, null);
}
}

您之前的代码有效,因为其消息长度为< = 160。但是另一条消息包含大于160个字符的url。要解决此问题,您需要以多个部分发送消息。使用下面给出的代码:
SmsManager sms = SmsManager.getDefault();
ArrayList<String> parts = sms.divideMessage(messageString);
sms.sendMultipartTextMessage(number, null, parts, null, null);
