我在使用2因素身份驗證創建應用程序時遇到了一些麻煩。我決定使用twilio作爲我的短信網關,並決定繼續他們的教程。不過,當我聲明一個URL發送短信的時候,我遇到了這個問題。出於某種原因,我不在乎有已經聲明 「mContext」無法解析getstring方法(java.lang.string)
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
import android.content.Context;
import java.io.IOException;
import okhttp3.Call;
import okhttp3.Callback;
import okhttp3.FormBody;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.RequestBody;
import okhttp3.Response;
public class MainActivity extends AppCompatActivity {
private EditText mTo;
private EditText mBody;
private Button mSend;
private OkHttpClient mClient = new OkHttpClient();
private Context mContext;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTo = (EditText) findViewById(R.id.txtNumber);
mBody = (EditText) findViewById(R.id.txtMessage);
mSend = (Button) findViewById(R.id.btnSend);
mSend.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
try {
post(mContext.getString(Integer.parseInt("http://4a61510d.grok.io/sms")),
new
Callback(){
@Override
public void onFailure(Call call, IOException e) {
e.printStackTrace();
}
@Override
public void onResponse(Call call, Response response) throws
IOException {
runOnUiThread(new Runnable() {
@Override
public void run() {
mTo.setText("");
mBody.setText("");
Toast.makeText(getApplicationContext(),"SMS
Sent!",Toast.LENGTH_SHORT).show();
}
});
}
});
} catch (IOException e) {
e.printStackTrace();
}
}
});
mContext = getApplicationContext();
}
Call post(String url, Callback callback) throws IOException {
RequestBody formBody = new FormBody.Builder()
.add("To", mTo.getText().toString())
.add("Body", mBody.getText().toString())
.build();
Request request = new Request.Builder()
.url(url)
.post(formBody)
.build();
Call response = mClient.newCall(request);
Response.**enqueue**(callback);
return response;
}}
我的build.gradle以及
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2',
{
exclude group: 'com.android.support', module: 'support-annotations'
})
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
compile 'com.squareup.okhttp3:okhttp:3.6.0'
和我的清單XML
<uses-permission android:name="android.permission.INTERNET"/>
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
這是怎麼得到一個錯誤我目前改變它仍然存在的錯誤
post(mContext.getString("http://4a61510d.ngrok.10/sms"), new Callback(){
仍然出現錯誤 – Wshivnarine
這就是我現在的 – Wshivnarine
@Wshivnarine刪除mContext.getString我的朋友。檢查我的答案 –
