BottomSheetDialog
来实现从底部弹出的对话框。以下是一个简单的实例代码:,,``java,import android.os.Bundle;,import androidx.appcompat.app.AppCompatActivity;,import com.google.android.material.bottomsheet.BottomSheetDialog;,,public class MainActivity extends AppCompatActivity {, @Override, protected void onCreate(Bundle savedInstanceState) {, super.onCreate(savedInstanceState);, setContentView(R.layout.activity_main);,, // 创建BottomSheetDialog实例, BottomSheetDialog bottomSheetDialog = new BottomSheetDialog(this);, , // 设置自定义布局, bottomSheetDialog.setContentView(R.layout.bottom_sheet_dialog);, , // 显示对话框, bottomSheetDialog.show();, },},
`,,在这个示例中,我们首先创建一个
BottomSheetDialog实例,然后通过
setContentView方法设置自定义的布局文件,最后调用
show`方法来显示对话框。Bitmap bitmap = Bitmap.createBitmap(view.getWidth(), view.getHeight(), Bitmap.Config.ARGB_8888);
获取屏幕截图,并使用FileOutputStream fos = new FileOutputStream("path/to/save");
保存到指定文件。SpeechRecognizer
类来处理语音输入。以下是一个简单的示例代码:,,``java,import android.content.Intent;,import android.os.Bundle;,import android.speech.RecognitionListener;,import android.speech.RecognizerIntent;,import android.speech.SpeechRecognizer;,import androidx.appcompat.app.AppCompatActivity;,import java.util.ArrayList;,,public class VoiceActivity extends AppCompatActivity {, private SpeechRecognizer speechRecognizer;,, @Override, protected void onCreate(Bundle savedInstanceState) {, super.onCreate(savedInstanceState);, setContentView(R.layout.activity_voice);,, speechRecognizer = SpeechRecognizer.createSpeechRecognizer(this);, speechRecognizer.setRecognitionListener(new RecognitionListener() {, @Override, public void onReadyForSpeech(Bundle params) {},, @Override, public void onBeginningOfSpeech() {},, @Override, public void onRmsChanged(float rmsdB) {},, @Override, public void onBufferReceived(byte[] buffer) {},, @Override, public void onEndOfSpeech() {},, @Override, public void onError(int error) {},, @Override, public void onResults(Bundle results) {, ArrayList matches = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);, if (matches != null && !matches.isEmpty()) {, String text = matches.get(0);, // 处理识别到的文本, }, },, @Override, public void onPartialResults(Bundle partialResults) {},, @Override, public void onEvent(int eventType, Bundle params) {}, });,, Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);, intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);, intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 1);, speechRecognizer.startListening(intent);, },, @Override, protected void onDestroy() {, super.onDestroy();, if (speechRecognizer != null) {, speechRecognizer.destroy();, }, },},
``,,这段代码创建了一个基本的语音识别界面,当用户说话时,会将识别到的文本进行处理。java,import com.google.mlkit.vision.common.InputImage;,import com.google.mlkit.vision.face.Face;,import com.google.mlkit.vision.face.FaceDetection;,import com.google.mlkit.vision.face.FaceDetector;,import com.google.mlkit.vision.face.FaceDetectorOptions;,,public void detectFaces(Bitmap bitmap) {, FaceDetectorOptions options = new FaceDetectorOptions.Builder(), .setPerformanceMode(FaceDetectorOptions.PERFORMANCE_MODE_ACCURATE), .setLandmarkMode(FaceDetectorOptions.LANDMARK_MODE_ALL), .setClassificationMode(FaceDetectorOptions.CLASSIFICATION_MODE_ALL), .build();,, InputImage image = InputImage.fromBitmap(bitmap, 0);, FaceDetector detector = FaceDetection.getClient(options);,, detector.process(image), .addOnSuccessListener(faces -> {, for (Face face : faces) {, // 处理检测到的人脸, }, }), .addOnFailureListener(e -> {, // 处理错误, });,},
``,,这段代码展示了如何使用ML Kit进行人脸检测,包括设置性能模式、地标模式和分类模式,并处理检测结果。Powered By Z-BlogPHP 1.7.3
