Question

我想在应用程序中更改不同意图的颜色。对于一个意图操作栏颜色为红色，对于其他一些意图，操作栏颜色为黄色。这是我的AndroidMenifest.xml，其中我更改了标签文本。但是如何更改该文本背景的背景与应用程序的主屏幕相同。

看起来我做了改变，但它不起作用。 `package com.example.android.miwok;

import android.app.Activity;
import android.content.Intent;
import android.graphics.Color;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Set the content of the activity to use the activity_main.xml layout 
file
    setContentView(R.layout.activity_main);

    TextView numbers = (TextView) findViewById(R.id.numbers);

// Set a click listener on that View
    numbers.setOnClickListener(new View.OnClickListener() {
        // The code in this method will be executed when the numbers View is 
clicked on.
        @Override
        public void onClick(View view) {
            Intent numbersIntent = new Intent(MainActivity.this, 
NumbersActivity.class);
            startActivity(numbersIntent);
            Intent i=new Intent(MainActivity.this,NumbersActivity.class);
            i.putExtra("toolbarColor", Color.BLUE);
        }
    });
    TextView family = (TextView) findViewById(R.id.family);

// Set a click listener on that View
    family.setOnClickListener(new View.OnClickListener() {
        // The code in this method will be executed when the family View is 
clicked on.
        @Override
        public void onClick(View view) {
            Intent familyIntent = new Intent(MainActivity.this, 
FamilyMembersActivity.class);
             startActivity(familyIntent);
        }
    });
    TextView colors = (TextView) findViewById(R.id.colors);

// Set a click listener on that View
    colors.setOnClickListener(new View.OnClickListener() {
        // The code in this method will be executed when the colors View is 
clicked on.

            startActivity(colorsIntent);
        }
    });

    pharses.setOnClickListener(new View.OnClickListener() {

Answer 1

这就是你想要的吗？如果是这样，请按照我的步骤。我会告诉你该怎么做。

首先，声明每个活动的样式。[res / values / styles.xml]

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <!-- other styles ... -->

    <style name="NumbersBg" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="colorPrimary">@color/colorPrimaryNumbers</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDarkNumbers</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

    <style name="FamilyMembersBg" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="colorPrimary">@color/colorPrimaryFamilyMembers</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDarkFamilyMembers</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

    <style name="ColorsBg" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="colorPrimary">@color/colorPrimaryColors</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDarkColors</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

    <style name="PhrasesBg" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="colorPrimary">@color/colorPrimaryPhrases</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDarkPhrases</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

</resources>

顺便说一句，上面提到的颜色应该在colors.xml [res / values / colors.xml]中更早地声明：

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <!-- other colors ... -->

    <!-- Numbers -->
    <color name="colorPrimaryNumbers">#fd8d28</color>
    <color name="colorPrimaryDarkNumbers">#AE611C</color>
    <!-- Family Members -->
    <color name="colorPrimaryFamilyMembers">#3b913c</color>
    <color name="colorPrimaryDarkFamilyMembers">#2C6B2C</color>
    <!-- Colors -->
    <color name="colorPrimaryColors">#87149e</color>
    <color name="colorPrimaryDarkColors">#4C0C59</color>
    <!-- Phrases -->
    <color name="colorPrimaryPhrases">#26afc8</color>
    <color name="colorPrimaryDarkPhrases">#186D7C</color>

</resources>

引用之前在AndroidManifest.xml中声明的样式。

<?xml version="1.0" encoding="utf-8"?>
<manifest>
    <application>

        <!-- other activities ... -->

        <activity
            android:name=".NumbersActivity"
            android:theme="@style/NumbersBg" />

        <activity
            android:name=".FamilyMembersActivity"
            android:theme="@style/FamilyMembersBg" />

        <activity
            android:name=".ColorsActivity"
            android:theme="@style/ColorsBg" />

        <activity
            android:name=".PhrasesActivity"
            android:theme="@style/PhrasesBg" />

    </application>
</manifest>

运行它。

Answer 2

您可以将颜色作为额外的颜色发送给活动。

Intent intent = ..;
intent.putExtra("toolbarColor", Color.BLUE);

在活动中，您希望工具栏颜色更改

int color = getIntent().getExtra("toolbarColor");
toolbar.setBackgroundDrawable(new ColorDrawable(color));

更改应用程序中不同意图的颜色
