我无法理解问题是什么！。

她是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？

MainActivity.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);
}
}

我试图解决它超过4天而且没有结果。请帮我！。谢谢先进

Answer 1

问题是它正在你的res / drawable /目录中寻找一个名为“abc_ic_ab_back_material.xml”的文件而它找不到它。确保您在该位置拥有该文件。

Answer 2

您在此处粘贴的代码未引用

abc_ic_ab_back_material

如果您在其他代码中使用过它，那么查找 res / drawable / 下的名为 abc_ic_ab_back_material 的资源，如果找不到，只需获取一个。
如果你没有在任何地方使用它，只需清理你投射并重建。
