硅谷社交4--设置页面

private void initData() {
	// 在button上显示当前用户名称
	bt_setting_out.setText("退出登录（" + EMClient.getInstance().getCurrentUser() + ")");
	// 退出登录的逻辑处理
	bt_setting_out.setOnClickListener(new View.OnClickListener() {
		@Override
		public void onClick(View v) {
			Model.getInstance().getGlobalThreadPool().execute(new Runnable() {
				@Override
				public void run() {
					// 登录环信服务器退出登录
					EMClient.getInstance().logout(false, new EMCallBack() {
						@Override
						public void onSuccess() {
							// 关闭DBHelper
							Model.getInstance().getDbManager().close();
							getActivity().runOnUiThread(new Runnable() {
								@Override
								public void run() {
									// 更新ui显示
									Toast.makeText(getActivity(), "退出成功", Toast.LENGTH_SHORT).show();
									// 回到登录页面
									Intent intent = new Intent(getActivity(), LoginAcitivity.class);
									startActivity(intent);
									getActivity().finish();
								}
							});
						}

						@Override
						public void onError(int i, final String s) {
							getActivity().runOnUiThread(new Runnable() {
								@Override
								public void run() {
									Toast.makeText(getActivity(), "退出失败" + s, Toast.LENGTH_SHORT).show();
								}
							});
						}

						@Override
						public void onProgress(int i, String s) {
						}
					});
				}
			});
		}
	});
}

用户名称变成大写解决办法(android:textAllCaps="false")

<Button
        android:id="@+id/bt_setting_out"
        android:text="退出"
        android:textSize="20sp"
        android:textAllCaps="false"
        android:textColor="@android:color/white"
        android:background="@android:color/holo_red_light"
        android:layout_width="match_parent"
        android:layout_height="60dp" />
