我想设计一个在不同分辨率的android手机中工作得很好的布局，例如给定的代码是布局代码我如何管理这个，所以它在各种不同分辨率的Android手机中都很好看。（分辨率就像480 * 800 768 * 1024等）任何人都可以帮助我
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/working_us"
android:layout_gravity="center_horizontal"
android:textColor="@color/heading"
android:textSize="20sp"/>
<TextView
android:layout_marginTop="20dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:text="@string/working_text"
android:layout_gravity="center_horizontal"

<Button

android:textColor="#51bdd4"

<Button

android:layout_margin="21dp"

android:text="DOWNLOAD THE APP"
android:textColor="#fff"

</LinearLayout>

您可以在res中创建不同的布局文件夹以获得小分辨率/大分辨率等，并将相同的副本放入不同的xml文件值
res/layout/main_activity.xml # For handsets (smaller than 600dp available width)
res/layout-sw600dp/main_activity.xml # For 7” tablets (600dp wide and bigger)
res/layout-sw720dp/main_activity.xml # For 10” tablets (720dp wide and bigger)
res/layout/main_activity.xml # For handsets (smaller than 600dp available width)
res/layout-w600dp/main_activity.xml # Multi-pane (any screen with 600dp available width or more)

如果要限制以下策略可以使用
如果您的应用仅适用于最小可用宽度为600dp的平板电脑型设备：
<manifest ... >
<supports-screens android:requiresSmallestWidthDp="600" />
...
</manifest>
或另一种替代方式是PercentRelativeLayout

从您对该问题的评论中可以明显看出，在许多小分辨率手机中，布局看起来不太好，您可以使用不同的布局来支持小分辨率手机。以下是步骤：
将所有维度与一个因子相乘会很繁琐，因此，您可以尝试my github repo，在输入因子值和项目位置后生成相应的维度文件内容。以下是参考代码：
package com.company;
import java.io.*;
import java.util.Scanner;
public class Main {
/**
* You can change your factors here. The current factors are just for the demo
*/
private static final double LDPI_FACTOR = 0.375;
private static final double MDPI_FACTOR = 0.5;
private static final double HDPI_FACTOR = 0.75;
private static final double XHDPI_FACTOR = 1.0;
private static final double XXHDPI_FACTOR = 1.5;
private static final double XXXHDPI_FACTOR = 2.0;
private static double factor;
public static void main(String[] args) throws IOException {
Scanner in = new Scanner(System.in);
System.out.println("Enter the location of the project/module");
String projectPath = in.nextLine();
System.out.println("Which of the following dimension file do you want?\n1. ldpi \n2. mdpi \n3. hdpi \n4. xhdpi \n5. xxhdpi \n6. xxxhdpi");
int dimenType = in.nextInt();
switch (dimenType) {
case 1: factor = LDPI_FACTOR;
break;
case 2: factor = MDPI_FACTOR;
break;
case 3: factor = HDPI_FACTOR;
break;
case 4: factor = XHDPI_FACTOR;
break;
case 5: factor = XXHDPI_FACTOR;
break;
case 6: factor = XXXHDPI_FACTOR;
break;
default:
factor = 1.0;
}
//full path = "/home/akeshwar/android-sat-bothIncluded-notintegrated/code/tpr-5-5-9/princetonReview/src/main/res/values/dimens.xml"
//location of the project or module = "/home/akeshwar/android-sat-bothIncluded-notintegrated/code/tpr-5-5-9/princetonReview/"
/**
* In case there is some I/O exception with the file, you can directly copy-paste the full path to the file here:
*/
String fullPath = projectPath + "/src/main/res/values/dimens.xml";
FileInputStream fstream = new FileInputStream(fullPath);
BufferedReader br = new BufferedReader(new InputStreamReader(fstream));
String strLine;
while ((strLine = br.readLine()) != null) {
modifyLine(strLine);
}
br.close();
}
private static void modifyLine(String line) {
/**
* Well, this is how I'm detecting if the line has some dimension value or not.
*/
if(line.contains("p</")) {
int endIndex = line.indexOf("p</");
//since indexOf returns the first instance of the occurring string. And, the actual dimension would follow after the first ">" in the screen
int begIndex = line.indexOf(">");
String prefix = line.substring(0, begIndex+1);
String root = line.substring(begIndex+1, endIndex-1);
String suffix = line.substring(endIndex-1,line.length());
/**
* Now, we have the root. We can use it to create different dimensions. Root is simply the dimension number.
*/
double dimens = Double.parseDouble(root);
dimens = dimens*factor*1000;
dimens = (double)((int)dimens);
dimens = dimens/1000;
root = dimens + "";
System.out.println(prefix + " " + root + " " + suffix );
}
System.out.println(line);
}
}

如果你想保持像素到像素的一致性，你需要在不同的值文件夹中维护尺寸文件，例如值-ldpi＆gt;＆gt;＆gt; dimens.xml，values-mdpi＆gt;＆gt;＆gt; dimens.xml，values- hdpi＆gt;＆gt;＆gt; dimens.xml，values-xhdpi＆gt;＆gt;＆gt; dimens.xml，values-xxhdpi＆gt;＆gt;＆gt; dimens.xml，values-xxxhdpi＆gt;＆gt;＆gt; dimens.xml并添加所需的dp或者根据分辨率的px值，你必须在所有文件夹中维护所有维度值的唯一名称，如10dp。
