php短視訊原始碼,SeekBar進度條滑動調節螢幕亮度實現的相關程式碼
1.佈局檔案
```cpp <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" android:gravity="center"> <TextView android:id="@+id/textview" android:layout_width="match_parent" android:layout_height="wrap_content" /> <SeekBar android:id="@+id/progress" android:layout_width="match_parent" android:layout_height="wrap_content" android:progressDrawable="@drawable/po_seekbar" android:thumb="@drawable/shape_circle" /> </LinearLayout> ```
2:佈局檔案所需的po_seekbar和shape_circle
po_seekbar檔案
```cpp <?xml version="1.0" encoding="utf-8"?> <layer-list xmlns:android="http://schemas.android.com/apk/res/android" > <item android:id="@android:id/background"> <shape> <solid android:color="#C9CAC5" /> <corners android:radius="10dip"/> </shape> </item> <item android:id="@android:id/secondaryProgress"> <clip> <shape> <corners android:radius="10dip"/> <solid android:color="#C9CAC5" /> </shape> </clip> </item> <item android:id="@android:id/progress"> <clip> <shape> <corners android:radius="10dip"/> <solid android:color="#FF5722" /> </shape> </clip> </item> </layer-list> ```
shape_circle檔案
```cpp <?xml version="1.0" encoding="utf-8"?> <!--seekbar的滑動塊樣式--> <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval"> <!--solid表示遠的填充色--> <solid android:color="#484848"></solid> <!--stroke代表遠的邊框線--> <stroke android:color="#484848" android:width="1dp" ></stroke> <!--size控制高寬--> <size android:width="24dp" android:height="24dp"></size> </shape> ```
3:主程式碼
```cpp public class MainActivity extends AppCompatActivity { //宣告拖動條 private SeekBar seekBar; private TextView textView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); textView = (TextView) findViewById(R.id.textview); seekBar = (SeekBar) findViewById(R.id.progress); seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() { @Override public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) { //當滑動條的位置發生改變時,觸發該方法,在這裡直接呼叫引數progress,即當前滑塊代表的進度值 textView.setText("Value" + Integer.toString(progress)); MainActivity.this.setScreenBrightness((float) seekBar.getProgress() / 100); } @Override public void onStartTrackingTouch(SeekBar seekBar) { } @Override public void onStopTrackingTouch(SeekBar seekBar) { } }); } private void setScreenBrightness(float num) { //取得螢幕的屬性 WindowManager.LayoutParams layoutParams = super.getWindow().getAttributes(); //設定螢幕的亮度 layoutParams.screenBrightness = num; //重新設定視窗的屬性 super.getWindow().setAttributes(layoutParams); } } ```
