app載入界面相關(guān)功能實(shí)現(xiàn)

模塊功能

1.設(shè)置頁面布局

2.初始化視頻播放

//控制是否跳到主界面private boolean isjump = false;private VideoView videoView;private void startSplash() {//播放地址Uri uri = Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.video);//初始化vdeoView對(duì)象videoView = findViewById(R.id.vv_splash);//設(shè)置視頻播放地址videoView.setVideoURI(uri);//開始播放videoView.start();videoView.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {@Overridepublic void onCompletion(MediaPlayer mp) {if(!isjump){//關(guān)閉當(dāng)前界面finish();startActivity(new Intent(SplashActivity.this,MainActivity.class));}}});}

3.跳過載入頁面功能

private void listenJumpBtn() {//初始化Button對(duì)象Button jump = findViewById(R.id.bt_jump);//綁定按鈕點(diǎn)擊事件jump.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {isjump = true;//關(guān)閉當(dāng)前界面finish();//跳轉(zhuǎn)到主界面startActivity(new Intent(SplashActivity.this,MainActivity.class));}});}

4.設(shè)置屏幕大小覆蓋全屏

private void setVideoSize() {//獲取屏幕尺寸對(duì)象DisplayMetrics displayMetrics = getResources().getDisplayMetrics();//創(chuàng)建布局參數(shù)RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(displayMetrics.widthPixels,displayMetrics.heightPixels);//設(shè)置給videoviewvideoView.setLayoutParams(params);//低版本模擬器上添加params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);params.addRule(RelativeLayout.ALIGN_PARENT_TOP);params.addRule(RelativeLayout.ALIGN_PARENT_LEFT);params.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);}
