java - Android 应用程序无法启动 Activity 组件信息 android.content.res.Resources$NotFound

Question

这是整个 logcat 堆栈跟踪:

我不明白这是什么问题!

这是 activity_main.xml

  <LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="16dp"
android:paddingRight="16dp"
android:paddingTop="16dp"
android:paddingBottom="16dp"
tools:context=".MainActivity"
android:orientation="vertical">

<TextView android:text="Quantity"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginBottom="16dp"
    />

<TextView
    android:id="@+id/quantity_text_view"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="0"
    android:layout_marginBottom="16dp"
    />
<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Button"
    android:onClick="SubmitOrder"
    />

</LinearLayout>

代码有什么问题吗？

主 Activity .java

package com.example.sham_tech.lastchance;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.TextView;

/**
 * This app displays an order form to order coffee.
 */
public class MainActivity extends AppCompatActivity {

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

/**
 * This method is called when the order button is clicked.
 */
public void submitOrder(View view) {
    display(1);
}

/**
 * This method displays the given quantity value on the screen.
 */
private void display(int number) {
    TextView quantityTextView = (TextView) findViewById(R.id.quantity_text_view);
    quantityTextView.setText("" + number);
}
}

我试了4天多没有结果。请帮助我!

问题是它正在您的 res/drawable/目录中寻找名为“abc_ic_ab_back_material.xml”的文件，但没有找到。确保该文件位于该位置。
