Question

如果单击一个按钮，我想显示三个图像按钮以显示Web视图。但是，当我通过线性布局创建三个图像按钮时，它不正常，因为我想显示我是否单击图像按钮菜单下的按钮。但是，现在，它将进入新的窗口。

我的webview.xml

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

   <Button
       android:id="@+id/imageButtonHomeSelector"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:background="@drawable/icon_home_config"
       android:onClick="imageButtonHomeSelector"


       />
<WebView
       android:id="@+id/webView1"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:layout_alignParentTop="true"
       android:layout_centerHorizontal="true"
       android:layout_marginTop="96dp" />

</RelativeLayout>

my mainactivity.java

public class MainActivity extends Activity {

private Button Homebutton, LoginButton, SettingButton;


  public void onCreate(Bundle savedInstanceState) {
    final Context context = this;

    super.onCreate(savedInstanceState);
    setContentView(R.layout.webview);

    Intent intent = new Intent(getApplicationContext(), WebViewActivity.class);

    startActivity(intent);


    addListenerHomeButton();
   // addListenerLoginButton();
   // addListenerSettingButton();

  }


 public void addListenerHomeButton() {

    Homebutton = (Button) findViewById(R.id.imageButtonHomeSelector);
    Homebutton.setFocusable(true);
    Homebutton.setFocusableInTouchMode(true);

    Homebutton.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {

            Intent intent = new Intent(getApplicationContext(), WebViewActivity.class);
            startActivity(intent);

        }

    });

}

  public void addListenerLoginButton() {

    LoginButton = (Button) findViewById(R.id.imageButtonLoginSelector);
    // LoginButton.setFocusable(true);
    LoginButton.setFocusableInTouchMode(true);

    LoginButton.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {

            Intent intent = new Intent(getApplicationContext(), LoginActivity.class);
            startActivity(intent);

        }

    });

  }

  public void addListenerSettingButton() {

     SettingButton = (Button) findViewById(R.id.imageButtonSettingSelector);

     SettingButton.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {

            Intent intent = new Intent(getApplicationContext(), SettingActivity.class);
            startActivity(intent);

         }

     });

   }
}

Answer 1

您要做的第一件事就是从onCreate

中删除这些行

public void onCreate(Bundle savedInstanceState) {
    final Context context = this;

    super.onCreate(savedInstanceState);
    setContentView(R.layout.webview);

    // You are starting the Activity always without doing anything else
    //Intent intent = new Intent(getApplicationContext(), WebViewActivity.class);

    //startActivity(intent);


    addListenerHomeButton();
   // addListenerLoginButton();
   // addListenerSettingButton();

}

然后您就可以点击按钮（如果可见）。
