【问题讨论】:
现在它也在 Currents 上。谷歌请求打开一个 API 或者说如何创建那个.. 【参考方案1】:这是我用来显示进度的代码:
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.Window;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class MainActivity extends Activity
WebView mWvUrl;
@Override
protected void onCreate(Bundle savedInstanceState)
final Activity activity=this;
super.onCreate(savedInstanceState);
getWindow().requestFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
setContentView(R.layout.activity_main);
activity.setProgressBarIndeterminateVisibility(false);
mWvUrl = (WebView) findViewById(R.id.wv_url);
mWvUrl.getSettings().setjavascriptEnabled(true);
Button btnLoad = (Button) findViewById(R.id.btn_load);
btnLoad.setOnClickListener(new OnClickListener()
@Override
public void onClick(View v)
EditText etUrl = (EditText) findViewById(R.id.et_url);
mWvUrl.loadUrl(etUrl.getText().toString());
activity.setProgressBarIndeterminateVisibility(true);
);
mWvUrl.setWebViewClient(new WebViewClient()
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
/** This prevents the loading of pages in system browser */
return false;
/** Callback method, executed when the page is completely loaded */
@Override
public void onPageFinished(WebView view, String url)
super.onPageFinished(view, url);
Toast.makeText(getBaseContext(),
"Page loaded Completely",
Toast.LENGTH_SHORT).show();
/** Hiding Indeterminate Progress Bar in the title bar*/
activity.setProgressBarIndeterminateVisibility(false);
);
@Override
public boolean onCreateOptionsMenu(Menu menu)
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
