如何使用 Button 的 onClickHandler 以最简单的方式切换到不同的页面(视图)?
这是主要活动:
package myapp.tabnavui;
import myapp.tabnavui.List1;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@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;
}
public void startClickHandler(View v) {
setContent(new Intent(this, Tabs3.class));
}
}
我想让 startClickHandler 使应用程序切换到 Tabs3:
package nl.computerhuys.tabnavui;
import android.app.TabActivity;
import android.os.Bundle;
import android.widget.TabHost;
import android.content.Intent;
/**
* An example of tab content that launches an activity via {@link android.widget.TabHost.TabSpec#setContent(android.content.Intent)}
*/
public class Tabs3 extends TabActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final TabHost tabHost = getTabHost();
tabHost.addTab(tabHost.newTabSpec("tab1")
.setIndicator("list")
.setContent(new Intent(this, List1.class)));
tabHost.addTab(tabHost.newTabSpec("tab2")
.setIndicator("photo list")
.setContent(new Intent(this, List8.class)));
// This tab sets the intent flag so that it is recreated each time
// the tab is clicked.
tabHost.addTab(tabHost.newTabSpec("tab3")
.setIndicator("destroy")
.setContent(new Intent(this, Controls2.class)
.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)));
}
}
我该怎么做(针对 Android 4,最低 Android 2.2)
