以下是具有意图数据的选项卡示例.

在调试时我发现总是在第一个选项卡中我们在tab选项卡中添加了tab主机

tabHost.addTab(tabHost.newTabSpec("tab1")
                    .setIndicator("list")
                    .setContent(new Intent(this, List1.class)));

即使我将tab2定义为当前选项卡如何解决这个问题,"List1"意图的oncreate方法也会被调用,无论它是否是我们当前的选项卡？

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).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)));

        // 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)));
    }
}

对于类RatingBar,我没有看到像setStyle这样的方法.如何从代码中设置评级样式？

Android:我想从麦克风中读取缓冲区,以便我可以对其执行处理,以下是我的代码

int sampleRateInHz = 8000;// 44100, 22050 and 11025
        int channelConfig = AudioFormat.CHANNEL_CONFIGURATION_MONO;
        int audioFormat = AudioFormat.ENCODING_PCM_16BIT;

        //int bufferSize =11025 + 
        int bufferSize = AudioRecord.getMinBufferSize(sampleRateInHz,channelConfig, audioFormat);


        short[] buffer = new short[bufferSize];

        AudioRecord audioRecord = new AudioRecord(MediaRecorder.AudioSource.MIC, sampleRateInHz,channelConfig, audioFormat, bufferSize);

        if(audioRecord.getState()== AudioRecord.STATE_INITIALIZED){
            audioRecord.startRecording();
            Log.e("recording", "before");


            boolean flag = true;
            while (flag) {
                int bufferReadResult = audioRecord.read(buffer, 0, bufferSize);
                System.out.println(buffer);
            }

            audioRecord.stop();
            audioRecord.release();
        }
        Log.e("recording", "stopeed");

我收到TypeError: Cannot read property 'forRoot' of undefined(…) 的时候我调查我发现,RouterModule是undefined 在执行过程中.

以下是我的app.route.ts

//const routes: Routes = [];
import {HelloComponent} from './hello.component';
import {IncComponent} from './inc.component';
import {AdditionComponent} from './addition.component';
import {RomanComponent} from './roman.component';

let routes: Routes = [

    {
        path: 'hello',
        component: HelloComponent
    },
    {
        path: '',
        redirectTo: '/hello',
        pathMatch: 'full'
    },
    {
        path: 'increment',
        component: IncComponent
    },{
        path: 'adder',
        component: AdditionComponent
    },{
