2. LoadingDialog代码
public class LoadingDialog extends Dialog { private AnimationDrawable mAnimation; private final String mLoadingTitle; private final int layout; public LoadingDialog(Context context, String content, int layout) { super(context); this.mLoadingTitle = content; this.layout = layout; //点击外围取消 setCanceledOnTouchOutside(true); } @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //设置窗口布局 setContentView(R.layout.progress_dialog); ImageView mImageView = findViewById(R.id.loadingIv); //设置动画资源 mImageView.setImageResource(layout); mAnimation = (AnimationDrawable) mImageView.getDrawable(); // 启动动态图话 mImageView.postDelayed(mAnimation::start, 100); TextView mLoadingTv = findViewById(R.id.loadingTv); //设置加载文字 mLoadingTv.setText(mLoadingTitle); // #00FFFFFF //设置透明 getWindow().setBackgroundDrawableResource(R.color.transparent); }}3. 调用窗口代码
public class MainActivity extends AppCompatActivity { private LoadingDialog loadingDialog; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); findViewById(R.id.show).setOnClickListener(v -> { if (loadingDialog == null) { //创建 loadingDialog = new LoadingDialog(MainActivity.this, "正在加载", R.drawable.anim_loading); } //调用 loadingDialog.show(); }); }}4.
