Question

I'm trying to make a simple SMS app and i keep getting this error

package com.example.daniel.sendmessage;

import android.content.Intent;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

public class MainActivity extends AppCompatActivity {

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

        final EditText phoneNumber = (EditText) findViewById(R.id.enterNumber);
        final EditText message = (EditText) findViewById(R.id.editText2);
        Button sendbtn = (Button) findViewById(R.id.button);

        sendbtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                Intent intent = new Intent(Intent.ACTION_VIEW);
                intent.setData(Uri.parse("smsto:"+phoneNumber.getText().toString()));
                intent.putExtra("sms_body", message.getText().toString());
                startActivity(intent);

            }
        });

    }
}

<resources>
    <string name="app_name">SendMessage</string> 
    <string name="phoneNumber">Enter Phone Number</string>
    <string name="sendbtn">Send</string>
</resources>

此错误与您的XML文件相关，请检查您的activity_main.xml也许您放置了某种会导致错误的drawable ，或者对于某些布局而言，您看错了XML-tag开始和结束位置，
