java - 无法初始化 Parse SDK 测试

Question

当我尝试运行应用程序来测试我的 SDK 是否已安装时，我得到

错误:(35, 22) 错误:没有找到合适的方法来初始化(,String,String)方法 Parse.initialize(Context,String,String) 不适用(实参无法通过方法调用转换转换为Context)方法 Parse.initialize(Context) 不适用(实际参数列表和正式参数列表的长度不同)

我按照所有说明进行操作，并检查了许多有关如何执行此操作的教程，但仍然收到此错误。

源代码:

package com.dusanp.passer;

import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.view.Menu;
import android.view.MenuItem;

import com.parse.Parse;
import com.parse.ParseObject;


public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    FloatingActionButton fab = (FloatingActionButton) 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();

            Parse.initialize(this, "zHpYwtZUDEHFuDULv2Vwt9rR0fie7fANFx7s24hT", "trnAIEthNLKkT6ueBP0ATYZh6pYhbpXFTN2gsSbP");

            ParseObject testObject = new ParseObject("TestObject");
            testObject.put("foo", "bar");
            testObject.saveInBackground();

        }
    });
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}

}

你的问题是这一行

Parse.initialize(this, "zHpYwtZUDEHFuDULv2Vwt9rR0fie7fANFx7s24hT", "trnAIEthNLKkT6ueBP0ATYZh6pYhbpXFTN2gsSbP");

在 onClickListener 中 this 指的是点击监听器，而不是 Pase sdk 对该参数所期望的上下文。如果您的 Activity 的名称是 MainActivity，则该行将如下所示。

Parse.initialize(MainActivity.this, "zHpYwtZUDEHFuDULv2Vwt9rR0fie7fANFx7s24hT", "trnAIEthNLKkT6ueBP0ATYZh6pYhbpXFTN2gsSbP");
