每周总结

调用html进行图形化展示

package com.example.app_t;

import androidx.appcompat.app.AppCompatActivity;

import android.content.Intent;
import android.os.Bundle;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class MainActivity3 extends AppCompatActivity {

    private WebView mWebView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main3);
        // 实例化
        mWebView = (WebView) findViewById(R.id.mWebView);

        // 开启javascript 渲染
        mWebView.getSettings().setJavaScriptEnabled(true);
        mWebView.setWebViewClient(new WebViewClient());


        Intent intent = getIntent();
        String name = intent.getStringExtra("name");


        // 载入内容
        mWebView.loadUrl("file:///android_asset/"+name+".html");

    }


}
