#DevTool 进阶配置
#接入 DevTool 开关页
我们提供了一个开关页，可以帮助你快速查看或者配置 DevTool。如果你需要，可以把它集成进 app。
DevTool 开关页使用 Lynx 编写，DevTool 组件中已经打包了该页面的产物。
开关页接入代码示例：
Objective-C
Swift
#import <Lynx/LynxView.h>
#import "DebugSettingViewController.h"
#import "DemoLynxProvider.h"
@implementation DebugSettingViewController
- (void)viewDidLoad {
[super viewDidLoad];
LynxView *lynxView = [[LynxView alloc] initWithBuilderBlock:^(LynxViewBuilder *builder) {
builder.config = [[LynxConfig alloc] initWithProvider:[[DemoLynxProvider alloc] init]];
builder.screenSize = self.view.frame.size;
builder.fontScale = 1.0;
}];
lynxView.preferredLayoutWidth = self.view.frame.size.width;
lynxView.preferredLayoutHeight = self.view.frame.size.height;
lynxView.layoutWidthMode = LynxViewSizeModeExact;
lynxView.layoutHeightMode = LynxViewSizeModeExact;
[self.view addSubview:lynxView];
NSString *bundlePath = [[NSBundle mainBundle] pathForResource:@"LynxDebugResources" ofType: @"bundle"];
NSData *templateData = [[NSData alloc] initWithContentsOfFile:[bundlePath stringByAppendingString:@"/switchPage/devtoolSwitch.lynx.bundle"]];
[lynxView loadTemplate:templateData withURL:@"devtool_switch/switchPage/devtoolSwitch.lynx.bundle"];
}
@end
Lynx DevTool 开关页使用 Lynx 编写，DevTool 组件中已经打包了该页面的产物。
开关页接入代码示例：
Java
Kotlin
public class SwitchActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
LynxView lynxView = buildLynxView();
setContentView(lynxView);
byte[] array = null;
try {
InputStream inputStream = this.getAssets().open("devtool_switch/switchPage/devtoolSwitch.lynx.bundle");
array = readBytes(inputStream);
lynxView.renderTemplateWithBaseUrl(array, TemplateData.empty(), "devtool_switch/switchPage/devtoolSwitch.lynx.bundle");
} catch (IOException e) {
e.printStackTrace();
}
}
private LynxView buildLynxView() {
LynxViewBuilder viewBuilder = new LynxViewBuilder();
viewBuilder.setTemplateProvider(new DemoTemplateProvider());
return viewBuilder.build(this);
}
private byte[] readBytes(InputStream inputStream) throws IOException {
byte[] buffer = new byte[1024];
int bytesRead;
ByteArrayOutputStream output = new ByteArrayOutputStream();
while ((bytesRead = inputStream.read(buffer)) != -1) {
output.write(buffer, 0, bytesRead);
}
return output.toByteArray();
}
}
Lynx DevTool 开关页使用 Lynx 编写，DevTool 组件中已经打包了该页面的产物。
开关页接入代码示例：
ETS
class Param {
url: string;
constructor(url: string) {
this.url = url;
}
}
@Entry
@Component
struct SwitchPage {
// ... existing code ...
build() {
Column() {
Text('Lynx').fontSize(18).width('100%').height('5%').textAlign(TextAlign.Center)
LynxView({
clients: this.clients,
url: this.url,
genericResourceFetcher: this.genericFetcher,
mediaResourceFetcher: this.mediaFetcher,
templateResourceFetcher: this.templateFetcher,
modules: this.modules,
sendableModules: this.sendableModules,
metaData: this.metaData,
onCreate: (context: LynxContext) => {
let param: Param = new Param(this.url);
context.sendGlobalEvent('viewAppear', [param]);
if (this.widthPixel > 0 && this.heightPixel > 0) {
context.updateScreenMetrics(this.widthPixel * this.viewDensity / TEST_DENSITY,
this.heightPixel * this.viewDensity / TEST_DENSITY);
}
context.setExtraTiming(this.extraTiming);
}
}).height(this.viewHeight).width(this.viewWidth)
}.size({ width: '100%', height: '100%' }).alignItems(HorizontalAlign.Start)
}
}
你也可以根据自己的需求，继续定制页面，让 DevTool 的配置更多样化。
