Question

好像我在使用

时遇到错误

@颜色/背景下， @ color / primary_dark ，以及的 @绘制/ source_but 即可。

Error:(32, 33) No resource found that matches the given name (at 'background' with value '@color/background').

Error:(44, 36) No resource found that matches the given name (at 'textColor' with value '@color/primary_dark').

Error:(121, 33) No resource found that matches the given name (at 'background' with value '@drawable/source_but').

我在源代码中创建了一个表单 https://developer.android.com/training/displaying-bitmaps/index.html

所以基本上我尝试将文本框和其他对象放入：

布局文件夹下的

image_detail_pager.xml。

以下是我尝试放置对象的方法：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <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="wrap_content"
            android:background="@color/background"
            android:orientation="vertical"
            tools:context="com.chalkstreet.learnandroid.main.Form">

            <TextView
                android:id="@+id/textViewHeader"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentTop="true"
                android:layout_centerHorizontal="true"
                android:padding="10dp"
                android:text="Fill the form and press the button to see the captured data."
                android:textColor="@color/primary_dark"
                android:textSize="16sp" />

            <EditText
                android:id="@+id/editText1"

            <EditText

            <EditText
                android:id="@+id/editText4"

        </LinearLayout>

        <Button

            android:background="@drawable/source_but"
            android:text="VIEW SOURCE CODE FOR ACTIVITY" />

    </RelativeLayout>

............................................... ..........................

我已经使用source_but.jpg更新了drawable，选择了我自己的图像。我更新了colors.xml。现在我有一个不同的错误！这里似乎有些不一致。

Error:(34, 24) No resource found that matches the given name


 (at 'label' 

with value '@string/title_activity_form').

DisplayingBitmaps/Application/build/
intermediates/manifests/full/debug/AndroidManifest.xml

finished with non-zero exit value 1

............................................... ........................

好的，我更新了Strings.xml，这是我最后的错误：

这是我的Form.java

public class Form extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_form);
        getSupportActionBar().setHomeButtonEnabled(true);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);

        //Initialize buttons and Edit Texts for form
        Button btnSubmit = (Button) findViewById(R.id.button_submit);
        Button btnSrc = (Button) findViewById(R.id.buttonSrc);
        final EditText name = (EditText) findViewById(R.id.editText1);
        final EditText email = (EditText) findViewById(R.id.editText2);
        final EditText phone = (EditText) findViewById(R.id.editText4);

        //Listener on Submit button
        btnSubmit.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent sender = new Intent(Form.this, com.chalkstreet.learnandroid.main.Display.class);
                Bundle b1 = new Bundle(); //Bundle to wrap all data
                b1.putString("name", name.getText().toString()); //Adding data to bundle
                b1.putString("email", email.getText().toString());
                b1.putString("phone", phone.getText().toString());
                sender.putExtras(b1); //putExtras method to send the bundle
                startActivity(sender);
                Form.this.finish(); //Finish form activity to remove it from stack
            }
        });

        //Listener on source button
        btnSrc.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent j = new Intent(Form.this, MainSource.class);
                startActivity(j);
            }
        });
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {

        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        int id = item.getItemId();
        if (id == android.R.id.home) {

            Form.this.finish();
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
}

以下是它给我的错误：

Error:(18, 32) error: cannot find symbol variable activity_form

Error:(33, 88) error: package com.chalkstreet.learnandroid.main does not exist

Error:(48, 50) error: cannot find symbol class MainSource

Error:(57, 41) error: cannot find symbol variable menu_main

Answer 1

在colors.xml文件中，您需要定义：

<color name="background">#FF0000</color>
<color name="primary_dark">#00FF00</color>

（使用您想要的颜色更改值）

然后，您需要将文件source_but添加到drawable文件夹中如果是图像，只需将其移动到那里。

将XML代码放入布局，pager.xml
