从抽屉调用活动时应用程序越来越近

Question

我是android开发的新手，我的应用程序在调用特定活动时会崩溃。（“governanaceactivity”是活动的名称）当我从MainActivity调用治理活动时，我的应用程序会崩溃，其他菜单工作得很好，唯一的问题是这个活动。

}

这是GovernanceActivity

package com.iridh.collegeapp;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class GovernanceActivity extends AppCompatActivity {

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

**所有其他活动都很好，只有这个活动有问题

这是我的宣言**

Answer 1

您必须将文件black.jpg重命名为black.XML，假设它是XML资源（如形状或选择器），或者将其重命名为black.png，假设它是图像。

那是你的错误：

Exception：二进制XML文件第288行导致类TextView膨胀错误：Android.content.res.resources$NotFoundException：drawable resource ID#0x7f08005c.XML扩展名中的文件res/drawable/black.jpg导致类TextView膨胀错误

以下是您的错误：

           <TextView
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_alignParentStart="true"
                android:layout_alignParentTop="true"
                android:gravity="center"
                android:text="Message"
                android:textSize="20dp"
                android:textColor="@drawable/black" <-- ERROR HERE
                android:textStyle="bold"
                app:fontFamily="@font/android"
                android:layout_alignParentLeft="true" />

您正在textcolor中设置drawable，并且应该是color资源。可以是@color/black(black应该在colors.xml中定义为 #000000 ，也可以是文字(Android:textcolor=“#000000”)。
