Question

我在使用Android Studio构建的Android应用程序上实现了一个启动画面，我想在启动画面中添加一个微调器。任何人都可以帮我解决这个问题：

这是我的splashScreen.java类的代码：

package com.packagename.appname;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Window;

/**
 * Created by VAIO1 on 05/09/2014.
 */
public class splashScreen extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.splash);
        Thread logoTimer = new Thread() {

            public void run() {
                    try {
                           sleep(3000);
                           Intent splashIntent = new Intent("com.packagename.appname.SPLASH");
                           startActivity(splashIntent);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    } finally {
                            finish();
                    }
               }

        };
        logoTimer.start();
    }

    @Override
    protected void onPause() {
        super.onPause();
    }

}

这是我的splash.xml的代码：

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:id="@+id/splashId">

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="center"
        android:src="@drawable/screen"
        android:cropToPadding="false"
        android:scaleType="fitXY"/>


</LinearLayout>

感谢您提供有关如何实现此目标的任何反馈。

use this code :-


public class splashScreen extends Activity {

ProgressDialog progressDialog;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.splash);
        Thread logoTimer = new Thread() {

            public void run() {
                    try {
                           sleep(3000);

                            progressDialog = new ProgressDialog(Sync_Screen_activity.this);
                            progressDialog.setMessage("Wait..");

                            progressDialog.setCancelable(false);
                            progressDialog.show();

                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    } finally {
                           Intent splashIntent = new Intent("com.packagename.appname.SPLASH");
                           startActivity(splashIntent);
                            finish();
                    }
               }

        };
        logoTimer.start();
    }

    @Override
    protected void onPause() {
        super.onPause();
    }

}
